minor surface irregularities and leave a uniform skid resistant application of material on the surface. The
spreader box and rear strike off shall be so designed and operated that a uniform consistency is achieved to
produce a free flow of material to the rear strike off. The longitudinal joint where two spreads join shall be neat
appearing, uniform, and lapped no more than six (6) inches. All excess material shall be removed from the job
site prior to opening the road. The spreader box shall have suitable means provided to side-shift the box to
compensate for variations in pavement geometry. The box shall be kept clean, and no build-up of asphalt and
aggregate shall be permitted. Spreader box skids shall be maintained in such a manner to prevent transverse
chatter (wash-boarding) in the finished mat. Any type drag used shall be approved by the Engineer and kept in
a completely flexible condition at all times.
6. Cleaning Equipment
Power brooms, power blowers, air compressors, water flushing equipment, and hand brooms suitable for
cleaning the base surface and cracks therein shall be provided by the Contractor in accordance with Section
01560 "Temporary Controls" and Section 02000 "Revision of Section 105; Maintenance During Construction".
7. Auxiliary Equipment

Contractor at no additional cost to the Owner.
Subsection 409.06 shall be revised as follows:
PREPARATION OF THE SURFACE
Immediately prior to application of the slurry, the Contractor shall be responsible for ensuring that the surface is
cleaned of all loose material, oil, silt spots, vegetation, and other objectionable material. Pavement cleaning
methods must be approved by the Engineer prior to use. The Contractor shall apply oil spot primers to oil, gas
and grease spots on pavement prior to applying the slurry seal. The Contractor must remove all weeds from
pavement surfaces and from the interface of the concrete curb and asphalt prior to the application of any slurry
seal. The Engineer shall give final approval that the surface has been prepared properly. Costs associated with
these requirements shall be included in the unit price of the slurry seal work and shall not be paid for separately
except as discussed in Section 02000 "Revision of Section 105; Maintenance During Construction".
If the slurry is being placed over a brick or concrete surface, a highly absorbent asphalt surface, areas subjected
to dusty conditions or over a surface where the aggregate has become exposed and is polished and slick, a one
part emulsion, three part water tack coat of the same emulsion type and grade as specified for the slurry is
recommended. This can be applied with an asphalt distributor. The normal application rate is 0.05 to 0.15
REVISION OF SECTION 409
ASPHALT SLURRY SEAL
Project Specifications – Page 12 of 28
gallons of the diluted emulsion per square yard of surface (0.23 to 0.70 liters per square meter). The Engineer
will have final authority to determine if tack coat is required and the rate at which it shall be applied.
The Owner will be performing concrete repair, patching, and crack sealing on the streets prior to the application
of the slurry seal.
Subsection 409.07 shall be revised as follows:
APPLICATION
The amount of asphalt emulsion to be blended with the aggregate shall be determined in the laboratory, subject
to final adjustment in the field to allow for absorption by the existing surface and approval by the Engineer.
The amount of water added must be controlled accurately to ensure production of readily spreadable, yet
completely stable slurry.
Proper water content shall be determined by an appropriate consistency test on freshly made slurry.
The slurry shall be a homogeneous mixture, sufficiently stable during the entire mixing - spreading period so
that the emulsion does not break, there is no segregation of fines from the coarser aggregate, and the liquid
portion of the mix does not float to the surface. Total time of mixing, from introduction of emulsion to
spreading shall be two minutes or less.
The weight of dry aggregate applied per unit area shall be 18 lbs/sy. The test sections shall be placed using the
same equipment and methods to be used on the job. Slurry mixtures placed in test strips shall conform to design
mix with minor variations to obtain crack filling, bond to pavement, and desired skid resistance texture. In the
event the materials do not meet the requirements for fluidity, non-segregation, or surface texture, a new job mix
shall be formulated and tested. Work shall not proceed before approval of a design mix and acceptance
following the placing of a test strip.
Application of the Slurry Surfaces
1. General
The surface shall be fogged with water directly preceding the spreader if required by local conditions as
directed by the Engineer. No free water shall be on the surface of the pavement following fog spray. Rate of
application of the fog spray shall be adjusted during the day to suit pavement temperatures, surface texture,
humidity, and dryness of pavement surface. The slurry mixtures shall be of the desired consistency as it leaves
the mixer, and no additional elements shall be added. A sufficient amount of slurry shall be carried in all parts
of the spreader at all times so that complete coverage is obtained. No lumping, balling, or unmixed aggregates
shall be permitted. No segregation of the emulsion and aggregate fines from the coarse aggregate will be
permitted. If the coarse aggregate settles to the bottom of the mix, the slurry will be removed from the
pavement. Breaking of the emulsion in the spreader box will not be allowed. No streaks as caused by
oversized aggregate will be left in the finished pavement. Rippling of the finished pavement is undesirable and
shall be minimized. The speed may be reduced by the Engineer, if rippling of the surface occurs. At any time
that segregation, texture, rippling or application rate are in non compliance with the specifications due to mix
equipment or workmanship, work will be stopped until the Owner's representative is insured that the non
conformance has been corrected.
After lay-down work is completed and before final acceptance by the Engineer, spot application of slurry seal
material may be required to correct any deficiencies such as streaking, scuff marks, tire tracks, gaps, etc. to
improve the ride quality and overall appearance. Slurry seal material required to correct deficiencies due to
unsatisfactory workmanship will not be paid for but shall be at the Contractor's expense.
REVISION OF SECTION 409
ASPHALT SLURRY SEAL
Project Specifications – Page 13 of 28
2. Joints
The longitudinal joint between adjacent lanes shall have no visible lap, pinholes, or uncovered areas. Build-up
or unsightly appearance shall be not be permitted on longitudinal or transverse joints. The use of burlap drags
or other type drags shall be at the direction of the Engineer. Thick spots caused by overlapping shall be
smoothed immediately with the hand squeegees before the emulsion breaks. Longitudinal joints shall be
overlapped no more than 6 inches over previously placed slurry. Slurry seal will be measured and paid for by
the square yard of street surface properly sealed and accepted by the Engineer. Building paper shall be used at
transverse joints to minimize or eliminate overlap. When drags are used, they must be kept clean and free of
build-up. Joints shall be straight and have a neat appearance.
3. Hand Work
Approved hand squeegees with burlap drags shall be used to spread slurry in areas not accessible to the slurry
mixer. Care shall be exercised as to the specified application rate and workmanship, as to leave no unsightly
appearance from hand work..
4. Mix Stability
The mixture shall possess sufficient stability so that premature breaking of the material in the spreader box does
not occur. The mixture shall be homogeneous during and following mixing and spreading, it shall be free of
excess water or emulsion and free of segregation of the emulsion and aggregate fines from the coarser
aggregate. Spraying of additional water into the spreader box will not be permitted.
5. Lines
Care shall be taken to ensure straight lines along curbs, shoulders and joints. No runoff on these areas will be
permitted. Lines at intersections will be kept straight to provide a neat appearance.
6. Curing
Slurry treated areas shall be allowed to cure until such time as the Engineer permits their opening to traffic. The
slurry seal mixture shall be proportioned to permit traffic on the newly sealed surface within 1 to 4 hours of
placement. The Contractor shall protect the area with suitable barricades for the full curing period, per the
approved traffic control plan.
7. Rolling
Slurry seal placed on parking lots, alleys, cul-de-sacs or low traffic volume areas, as determined by the
Engineer, shall be rolled with a pneumatic tire roller with a minimum weight of four (4) tons. Rolling shall start
when the slurry seal has set sufficiently to prevent any pick-up of material and rolled a minimum of three (3)
coverages by the roller until a uniform surface is obtained. Payment for rolling will not be measured or paid for
separately, but shall be included in the unit price for Slurry Seal.
8. Maintaining Traffic
The seal coat shall be applied to alternating streets to provide sufficient public parking for those residents living
on streets which have been closed. Traffic will not be allowed on the newly placed bituminous material until, in
the opinion of the Engineer, the bituminous material has sufficiently set and bonded to prevent damage by
vehicular traffic. Areas which are subject to an increased rate of sharp turning vehicles may require additional
time to allow for a more complete cure of the slurry seal mat to prevent damage. Street closures shall be opened
as soon as the material has sufficiently set and bonded.

Rolling (Chipseal): Initial rolling shall begin immediately after the application of cover coat aggregate. Rollers shall
work in tandem and complete a minimum of three passes with a sufficient overlap. Should the rolling operation be
delayed, the aggregate and emulsion spreading shall be halted until the operation regains proper sequencing and timing.
The maximum speed of the rolling operations shall be ten miles per hour.
Sweeping (Chipseal): Within 24 hours of the Slurry application, excess aggregate shall be swept and removed from
the roadway and adjacent areas with specified herein sweepers.
Application of Material (Slurry): Within 48 hours of the chipseal application the slurry course will be applied. The
surface shall be fogged with water directly preceding the spreader. The slurry mixtures shall be of the desired
consistency, based on the submitted mix design, as it leaves the mixer with additional approved additive if required. A
sufficient amount of slurry shall be carried in all parts of the spreader at all times so that complete coverage is obtained.
No lumping, balling, or unmixed aggregates shall be permitted. No segregation of the emulsion and aggregate fines from
the coarse aggregate will be permitted. No excessive breaking of the emulsion will be allowed in the spreader box.
Rippling of the finished pavement is undesirable and shall be minimized. No excessive build-up or unsightly appearance
shall be permitted on longitudinal or transverse joints. The use of burlap drags or other type drags shall be used so that
joints will be straight and have a neat appearance. Squeegees shall be used to spread slurry in areas not accessible to the
slurry mixer. Care shall be exercised as the leave a good appearance. Care shall be taken to insure straight lines along
curbs, shoulders and joints. Lines at intersections will be kept straight to provide a good appearance.

Section 630 of the Standard Specifications is hereby revised as follows:
DESCRIPTION
Subsection 630.01 shall be revised as follows:
This work shall consist of furnishing, installing, moving maintaining and removing temporary traffic signs,
advance warning arrows panels, barricades, channelizing devices, and delineators as required by the latest
revision of the "Manual on Uniform Traffic Control Devices for Streets and Highways" (MUTCD), the City of
Fort Collins “Work Area Traffic Control Handbook", and the Larimer County Urban Area Street Standards.
In the event of a conflict between the MUTCD criteria and the City's criteria, the City's criteria shall govern.
When a device is not in use, the Contractor shall remove it from the project for the period it is not needed.
Devices temporarily not in use shall, as a minimum, be removed from the area. Moving will include devices
removed from the project and later returned to use. The City of Fort Collins shall pay for the maximum number
of each type of traffic control device being used at one given time per day. Larimer County shall pay for
Construction Zone Traffic Control lump sum.
Traffic control devices shall be placed and/or stored in the right-of-way in such a manner that minimizes the
hazards to pedestrians, bicyclists and vehicles.
Traffic control devices shall be removed from the site immediately upon completion of the work for any
street(s).
MATERIALS
Subsection 630.02 shall include the following:
All traffic control devices placed for this project must meet or exceed the minimum standards set forth in the
MUTCD. All traffic control devices shall be clean and in good operating condition when delivered and shall be
maintained in that manner on a daily basis. All traffic control devices shall be clearly marked and free of
crossed out information or any other form of defacement that detracts from the purpose for which they are
intended (i.e. crossed out information, information written in long-hand style, etc.)
Additionally, any sign blank with sign faces on both sides must have the back sign face covered when in use to
avoid confusion to motorists traveling in the opposite direction and other potentially affected parties, such as
residents affected by any information the sign may present.
CONSTRUCTION REQUIREMENTS
Subsection 630.09 shall be revised as follows:
TRAFFIC CONTROL PLAN
Traffic control through the construction areas is the responsibility of the Contractor.
For all locations, a Traffic Control Plan shall be prepared. The Traffic Control Plans for the City of Fort Collins
shall be on City supplied forms. The Traffic Control Plans shall be submitted for approval to the Engineer by
8:00 a.m., two working days prior to the commencement of work. (Note: Traffic Control Plans for work done
on Monday and Tuesday shall be submitted the previous Friday by 8:00 a.m.) Full road closure plans shall be
REVISION OF SECTION 630
CONSTRUCTION ZONE TRAFFIC CONTROL
Project Specifications – Page 22 of 28
submitted no later than Friday mornings by 8:00 a.m. for projects starting the following week. All plans shall
be delivered to City Engineering, 281 North College Avenue. Facsimiles of plans shall not be allowed. No
phase of the construction shall start until the Traffic Control Plan has been approved. Failure to have an
approved Traffic Control Plan shall constitute cause for the City to stop work, as well as the Contractor's
forfeiture of payment for all work and materials at that location, with no adjustment in the contract time.
All costs associated with Traffic Control Plan review will not be measured or paid for separately, but shall be
considered incidental to the Work.
The Traffic Control Plan shall include, as a minimum, the following:
(1) A detailed diagram which shows the location of all sign placements, including advance construction
signs (if not previously approved) and speed limit signs; method, length and time duration for lane
closures, and location of flag persons.

construction signs; vertical panel; vertical panel with light; Type I, Type II, and Type III barricades;
cones; drum channelizing devices; advance warning flashing or sequencing arrow panel. Certain
traffic control devices may be used for more than one operation or phase. However, all devices
required for any particular phase must be detailed and tabulated for each phase.
(3) Number of flaggers to be used.
(4) Parking Restrictions to be in affect.
Approval of the proposed method of handling traffic is intended to indicate those devices for which payment is
to be made. Such approval does not relieve the Contractor of liability specifically assigned to him under this
contract.
Parking Restriction Plans for the City of Fort Collins shall be submitted and approved which show the location
and quantity of "NO PARKING" signs, the date to be placed, and the date to be removed. The plans shall be
prepared on City supplied forms. The Parking Restriction Plans shall be submitted to the Engineer by 8:00

with a temperature indicating device installed in the emulsion tank at the emulsion pump suction line level. The
aggregate shall be pre-wetted immediately prior to mixing with the emulsion. The mixing unit shall be capable
of thoroughly blending all ingredients together without violent action. The mixing machine shall be equipped
with an approved fines feeder that provides an accurate metering device or method of introducing a
predetermined proportion of mineral filler into the mixer as the aggregate is fed in. The fines feeder shall be
used when mineral filler is part of the aggregate blend. The unit shall be equipped with approved devices so
that the machine can be accurately calibrated and the quantities of materials used during any one period
estimated. The mixing machine shall be equipped with a water pressure system, and fog type spray bar
adequate for completely fogging the surface with up to 0.055 gallons per square yard (0.25 l/m2), immediately
ahead of the spreading equipment. The machine shall be capable of mixing materials at preset proportions
regardless of the speed of the machine engine, and without changing machine settings.
2. Proportioning Devices
Individual volume or weight controls for proportioning each material to be added to the mix (i.e., aggregate,
mineral filler, emulsified asphalt and water) shall be provided and properly marked. These proportioning
devices are usually revolution counters or similar devices and are used in material calibration and determining
the materials output at any time. Yield estimates with supporting documentation from the metering devices and
material delivery tickets will be provided by the Contractor daily.
3. Calibration
Each slurry mixing unit to be used in performance of the work shall be calibrated in the presence of the
Engineer's representative prior to construction. The documentation shall be provided, which includes an
individual calibration of each material at various settings, which can be related to the machine's metering
device(s). No machine will be allowed to work on the project until the calibration has been completed and
accepted by the Engineer.

When the test sections do not conform to the specification requirements, the slurry seal shall be removed at the
Contractor’s expense. No compensation will be made for re-application or additional test sections required due
to unsatisfactory work or material. Initiation of work on the project streets shall not begin without the
Engineer’s approval of test sections.
5. Slurry Spreading Equipment
The surfacing mixture shall be spread uniformly by means of a mechanical type squeegee distributor, having a
rubber-like material in contact with the surface to prevent unwanted egress of slurry. It shall prevent loss of
slurry on varying grades and crown by adjustments to assure uniform spread. An appropriate mechanical device
for lateral distribution of the slurry shall be operated within the spreader box. There shall be a steering device, a
flexible strike-off, and a burlap or other approved drag. The spreader box shall be equipped with paddles or
augers to agitate and spread the materials throughout the box. It shall be capable of producing a uniform
surface its full width. A front seal shall be provided to ensure no loss of the mixture at the road contact point.
The rear seal shall act as final strike off and shall be adjustable. The mixture shall be spread to fill cracks and
minor surface irregularities and leave a uniform skid resistant application of material on the surface. The
spreader box and rear strike off shall be so designed and operated that a uniform consistency is achieved to
produce a free flow of material to the rear strike off. The longitudinal joint where two spreads join shall be neat
appearing, uniform, and lapped no more than six (6) inches. All excess material shall be removed from the job
site prior to opening the road. The spreader box shall have suitable means provided to side-shift the box to
compensate for variations in pavement geometry. The box shall be kept clean, and no build-up of asphalt and
aggregate shall be permitted. Spreader box skids shall be maintained in such a manner to prevent transverse
chatter (wash-boarding) in the finished mat. Any type drag used shall be approved by the Engineer and kept in
a completely flexible condition at all times.
6. Cleaning Equipment
Power brooms, power blowers, air compressors, water flushing equipment, and hand brooms suitable for
cleaning the base surface and cracks therein shall be provided by the Contractor in accordance with Section
01560 "Temporary Controls" and Section 02000 "Revision of Section 105; Maintenance During Construction".
7. Auxiliary Equipment
Hand squeegees, shovels and all other equipment necessary to perform the work shall be provided by the
Contractor at no additional cost to the Owner.
Subsection 409.06 shall be revised as follows:
PREPARATION OF THE SURFACE
Immediately prior to application of the slurry, the Contractor shall be responsible for ensuring that the surface is
cleaned of all loose material, oil, silt spots, vegetation, and other objectionable material. Pavement cleaning
methods must be approved by the Engineer prior to use. The Contractor shall apply oil spot primers to oil, gas
and grease spots on pavement prior to applying the slurry seal. The Contractor must remove all weeds from
pavement surfaces and from the interface of the concrete curb and asphalt prior to the application of any slurry
seal. The Engineer shall give final approval that the surface has been prepared properly. Costs associated with
these requirements shall be included in the unit price of the slurry seal work and shall not be paid for separately
except as discussed in Section 02000 "Revision of Section 105; Maintenance During Construction".
If the slurry is being placed over a brick or concrete surface, a highly absorbent asphalt surface, areas subjected
to dusty conditions or over a surface where the aggregate has become exposed and is polished and slick, a one
part emulsion, three part water tack coat of the same emulsion type and grade as specified for the slurry is
recommended. This can be applied with an asphalt distributor. The normal application rate is 0.05 to 0.15
REVISION OF SECTION 409
ASPHALT SLURRY SEAL
Project Specifications – Page 12 of 28
gallons of the diluted emulsion per square yard of surface (0.23 to 0.70 liters per square meter). The Engineer
will have final authority to determine if tack coat is required and the rate at which it shall be applied.
The Owner will be performing concrete repair, patching, and crack sealing on the streets prior to the application
of the slurry seal.
Subsection 409.07 shall be revised as follows:
APPLICATION
The amount of asphalt emulsion to be blended with the aggregate shall be determined in the laboratory, subject
to final adjustment in the field to allow for absorption by the existing surface and approval by the Engineer.
The amount of water added must be controlled accurately to ensure production of readily spreadable, yet
completely stable slurry.
Proper water content shall be determined by an appropriate consistency test on freshly made slurry.
The slurry shall be a homogeneous mixture, sufficiently stable during the entire mixing - spreading period so
that the emulsion does not break, there is no segregation of fines from the coarser aggregate, and the liquid
portion of the mix does not float to the surface. Total time of mixing, from introduction of emulsion to
spreading shall be two minutes or less.
The weight of dry aggregate applied per unit area shall be 18 lbs/sy. The test sections shall be placed using the
same equipment and methods to be used on the job. Slurry mixtures placed in test strips shall conform to design
mix with minor variations to obtain crack filling, bond to pavement, and desired skid resistance texture. In the
event the materials do not meet the requirements for fluidity, non-segregation, or surface texture, a new job mix
shall be formulated and tested. Work shall not proceed before approval of a design mix and acceptance
following the placing of a test strip.
Application of the Slurry Surfaces
1. General
The surface shall be fogged with water directly preceding the spreader if required by local conditions as
directed by the Engineer. No free water shall be on the surface of the pavement following fog spray. Rate of
application of the fog spray shall be adjusted during the day to suit pavement temperatures, surface texture,
humidity, and dryness of pavement surface. The slurry mixtures shall be of the desired consistency as it leaves
the mixer, and no additional elements shall be added. A sufficient amount of slurry shall be carried in all parts
of the spreader at all times so that complete coverage is obtained. No lumping, balling, or unmixed aggregates
shall be permitted. No segregation of the emulsion and aggregate fines from the coarse aggregate will be
permitted. If the coarse aggregate settles to the bottom of the mix, the slurry will be removed from the
pavement. Breaking of the emulsion in the spreader box will not be allowed. No streaks as caused by
oversized aggregate will be left in the finished pavement. Rippling of the finished pavement is undesirable and
shall be minimized. The speed may be reduced by the Engineer, if rippling of the surface occurs. At any time
that segregation, texture, rippling or application rate are in non compliance with the specifications due to mix
equipment or workmanship, work will be stopped until the Owner's representative is insured that the non
conformance has been corrected.
After lay-down work is completed and before final acceptance by the Engineer, spot application of slurry seal
material may be required to correct any deficiencies such as streaking, scuff marks, tire tracks, gaps, etc. to
improve the ride quality and overall appearance. Slurry seal material required to correct deficiencies due to
unsatisfactory workmanship will not be paid for but shall be at the Contractor's expense.
REVISION OF SECTION 409
ASPHALT SLURRY SEAL
Project Specifications – Page 13 of 28
2. Joints
The longitudinal joint between adjacent lanes shall have no visible lap, pinholes, or uncovered areas. Build-up
or unsightly appearance shall be not be permitted on longitudinal or transverse joints. The use of burlap drags
or other type drags shall be at the direction of the Engineer. Thick spots caused by overlapping shall be
smoothed immediately with the hand squeegees before the emulsion breaks. Longitudinal joints shall be
overlapped no more than 6 inches over previously placed slurry. Slurry seal will be measured and paid for by
the square yard of street surface properly sealed and accepted by the Engineer. Building paper shall be used at
transverse joints to minimize or eliminate overlap. When drags are used, they must be kept clean and free of
build-up. Joints shall be straight and have a neat appearance.
3. Hand Work
Approved hand squeegees with burlap drags shall be used to spread slurry in areas not accessible to the slurry
mixer. Care shall be exercised as to the specified application rate and workmanship, as to leave no unsightly
appearance from hand work..
4. Mix Stability
The mixture shall possess sufficient stability so that premature breaking of the material in the spreader box does
not occur. The mixture shall be homogeneous during and following mixing and spreading, it shall be free of
excess water or emulsion and free of segregation of the emulsion and aggregate fines from the coarser
aggregate. Spraying of additional water into the spreader box will not be permitted.
5. Lines
Care shall be taken to ensure straight lines along curbs, shoulders and joints. No runoff on these areas will be
permitted. Lines at intersections will be kept straight to provide a neat appearance.
6. Curing
Slurry treated areas shall be allowed to cure until such time as the Engineer permits their opening to traffic. The
slurry seal mixture shall be proportioned to permit traffic on the newly sealed surface within 1 to 4 hours of
placement. The Contractor shall protect the area with suitable barricades for the full curing period, per the
approved traffic control plan.
7. Rolling
Slurry seal placed on parking lots, alleys, cul-de-sacs or low traffic volume areas, as determined by the
Engineer, shall be rolled with a pneumatic tire roller with a minimum weight of four (4) tons. Rolling shall start
when the slurry seal has set sufficiently to prevent any pick-up of material and rolled a minimum of three (3)
coverages by the roller until a uniform surface is obtained. Payment for rolling will not be measured or paid for
separately, but shall be included in the unit price for Slurry Seal.
8. Maintaining Traffic
The seal coat shall be applied to alternating streets to provide sufficient public parking for those residents living
on streets which have been closed. Traffic will not be allowed on the newly placed bituminous material until, in
the opinion of the Engineer, the bituminous material has sufficiently set and bonded to prevent damage by
vehicular traffic. Areas which are subject to an increased rate of sharp turning vehicles may require additional
time to allow for a more complete cure of the slurry seal mat to prevent damage. Street closures shall be opened
as soon as the material has sufficiently set and bonded.

covered in a suitable manner prior to sealing, and the covering shall be removed immediately after the street is
sealed. The Contractor shall submit the method for protecting manholes and valves to the Engineer for approval
at least two weeks prior to commencement of work. After sealing, the Contractor shall verify accessibility to
manholes and valves to the satisfaction of the Engineer at the end of each day. Manholes and valves shall be
marked by the Contractor prior to placing the slurry to insure each one is located and can be found after slurry
sealing.
10. Stockpiles and Equipment Storage
The Contractor is solely responsible for finding and using suitable stockpile locations. The Owner shall be
allowed access to the stockpile locations at all times. No portion of the right of way may be used for storage
of materials or equipment. Materials shall be stored in an area to prevent water saturation and contamination
of stockpiled aggregates. On-site emulsion tanks shall be empty and cleaned of all residual asphalt prior to
delivery of the first load of approved emulsion. Written authorization to use private property to store equipment
and materials shall be obtained from the property owner and submitted prior to mobilization and use. The
Contractor shall also submit a letter of indemnification to the Owner and the property owner.
11. Cleanup
All material swept or blown onto sidewalks, all trash, all discarded slurry seal material, or other refuse shall be
collected on a daily basis, removed from the site, and disposed of to a site approved by the Engineer.
All applied slurry surfaces shall be swept by an approved sweeper to remove any excess raveled material which
becomes dislodged from the street surface after five (5) days. Dislodged material from the street shall be
disposed of to a site approved by the Engineer. Payment for sweeping shall be paid for separately as described
in Section 02000 "Revision of Section 105; Maintenance During Construction". Excessive raveling, as
determined by the Engineer, shall be swept by the Contractor at no additional cost to the Owner.

rejection. It is the responsibility of the Contractor, at his own expense, to prove to the Engineer that the
conditions have been corrected before work may continue. See Section 01400 "Quality Control".
METHOD OF MEASUREMENT
Subsection 409.09 shall be revised as follows:
Slurry seal will be measured and paid for by the square yard of street surface properly sealed and accepted by
the Engineer. This payment will be full compensation for preparing street surfaces, furnishing all labor,
material, tools, equipment, incidentals and for all the work involved in placing the mix, including rolling and oil
spot primer. Any additional additives used by the Contractor must be approved by the Engineer. No separate
payment for additional additives will be made unless approved prior to use by the Engineer.
It is imperative that the Engineer's representative be present at the time of delivery of all materials.
Conformance with application rates will be determined from delivery tickets, minus any excess material not
used on the project. It is the Contractor's responsibility to notify the Engineer 24 hours prior to delivery of
materials so that a representative may be present. No payment will be made for materials delivered without
proper notification.
Proportions of the material components to be used will be set by the Engineer, as well as the spread rate. These
will be defined in the project mix design.
Application rates will be set to match the approved mix design. If the yield is determined to be in excess of the
maximum application rates, or below the minimum application rates, the slurry seal will be subject to rejection
or a price reduction as follows at the direction of the Engineer:
AMOUNT BELOW MINIMUM

Engineer’s approval of test sections.
5. Slurry Spreading Equipment
The surfacing mixture shall be spread uniformly by means of a mechanical type squeegee distributor, having a
rubber-like material in contact with the surface to prevent unwanted egress of slurry. It shall prevent loss of
slurry on varying grades and crown by adjustments to assure uniform spread. An appropriate mechanical device
for lateral distribution of the slurry shall be operated within the spreader box. There shall be a steering device, a
flexible strike-off, and a burlap or other approved drag. The spreader box shall be equipped with paddles or
augers to agitate and spread the materials throughout the box. It shall be capable of producing a uniform
surface its full width. A front seal shall be provided to ensure no loss of the mixture at the road contact point.
The rear seal shall act as final strike off and shall be adjustable. The mixture shall be spread to fill cracks and
minor surface irregularities and leave a uniform skid resistant application of material on the surface. The
spreader box and rear strike off shall be so designed and operated that a uniform consistency is achieved to
produce a free flow of material to the rear strike off. The longitudinal joint where two spreads join shall be neat
appearing, uniform, and lapped no more than six (6) inches. All excess material shall be removed from the job
site prior to opening the road. The spreader box shall have suitable means provided to side-shift the box to
compensate for variations in pavement geometry. The box shall be kept clean, and no build-up of asphalt and
aggregate shall be permitted. Spreader box skids shall be maintained in such a manner to prevent transverse
chatter (wash-boarding) in the finished mat. Any type drag used shall be approved by the Engineer and kept in
a completely flexible condition at all times.
6. Cleaning Equipment
Power brooms, power blowers, air compressors, water flushing equipment, and hand brooms suitable for
cleaning the base surface and cracks therein shall be provided by the Contractor in accordance with Section

Contractor at no additional cost to the Owner.
Subsection 409.06 shall be revised as follows:
PREPARATION OF THE SURFACE
Immediately prior to application of the slurry, the Contractor shall be responsible for ensuring that the surface is
cleaned of all loose material, oil, silt spots, vegetation, and other objectionable material. Pavement cleaning
methods must be approved by the Engineer prior to use. The Contractor shall apply oil spot primers to oil, gas
and grease spots on pavement prior to applying the slurry seal. The Contractor must remove all weeds from
pavement surfaces and from the interface of the concrete curb and asphalt prior to the application of any slurry
seal. The Engineer shall give final approval that the surface has been prepared properly. Costs associated with
these requirements shall be included in the unit price of the slurry seal work and shall not be paid for separately
except as discussed in Section 02000 "Revision of Section 105; Maintenance During Construction".
If the slurry is being placed over a brick or concrete surface, a highly absorbent asphalt surface, areas subjected
to dusty conditions or over a surface where the aggregate has become exposed and is polished and slick, a one
part emulsion, three part water tack coat of the same emulsion type and grade as specified for the slurry is
recommended. This can be applied with an asphalt distributor. The normal application rate is 0.05 to 0.15
REVISION OF SECTION 409
ASPHALT SLURRY SEAL
Project Specifications – Page 12 of 28
gallons of the diluted emulsion per square yard of surface (0.23 to 0.70 liters per square meter). The Engineer
will have final authority to determine if tack coat is required and the rate at which it shall be applied.
The Owner will be performing concrete repair, patching, and crack sealing on the streets prior to the application
of the slurry seal.
Subsection 409.07 shall be revised as follows:
APPLICATION
The amount of asphalt emulsion to be blended with the aggregate shall be determined in the laboratory, subject
to final adjustment in the field to allow for absorption by the existing surface and approval by the Engineer.
The amount of water added must be controlled accurately to ensure production of readily spreadable, yet
completely stable slurry.
Proper water content shall be determined by an appropriate consistency test on freshly made slurry.
The slurry shall be a homogeneous mixture, sufficiently stable during the entire mixing - spreading period so
that the emulsion does not break, there is no segregation of fines from the coarser aggregate, and the liquid
portion of the mix does not float to the surface. Total time of mixing, from introduction of emulsion to
spreading shall be two minutes or less.
The weight of dry aggregate applied per unit area shall be 18 lbs/sy. The test sections shall be placed using the
same equipment and methods to be used on the job. Slurry mixtures placed in test strips shall conform to design
mix with minor variations to obtain crack filling, bond to pavement, and desired skid resistance texture. In the
event the materials do not meet the requirements for fluidity, non-segregation, or surface texture, a new job mix
shall be formulated and tested. Work shall not proceed before approval of a design mix and acceptance
following the placing of a test strip.
Application of the Slurry Surfaces
1. General
The surface shall be fogged with water directly preceding the spreader if required by local conditions as
directed by the Engineer. No free water shall be on the surface of the pavement following fog spray. Rate of
application of the fog spray shall be adjusted during the day to suit pavement temperatures, surface texture,
humidity, and dryness of pavement surface. The slurry mixtures shall be of the desired consistency as it leaves
the mixer, and no additional elements shall be added. A sufficient amount of slurry shall be carried in all parts
of the spreader at all times so that complete coverage is obtained. No lumping, balling, or unmixed aggregates
shall be permitted. No segregation of the emulsion and aggregate fines from the coarse aggregate will be
permitted. If the coarse aggregate settles to the bottom of the mix, the slurry will be removed from the
pavement. Breaking of the emulsion in the spreader box will not be allowed. No streaks as caused by
oversized aggregate will be left in the finished pavement. Rippling of the finished pavement is undesirable and
shall be minimized. The speed may be reduced by the Engineer, if rippling of the surface occurs. At any time
that segregation, texture, rippling or application rate are in non compliance with the specifications due to mix
equipment or workmanship, work will be stopped until the Owner's representative is insured that the non
conformance has been corrected.
After lay-down work is completed and before final acceptance by the Engineer, spot application of slurry seal
material may be required to correct any deficiencies such as streaking, scuff marks, tire tracks, gaps, etc. to
improve the ride quality and overall appearance. Slurry seal material required to correct deficiencies due to
unsatisfactory workmanship will not be paid for but shall be at the Contractor's expense.

or unsightly appearance shall be not be permitted on longitudinal or transverse joints. The use of burlap drags
or other type drags shall be at the direction of the Engineer. Thick spots caused by overlapping shall be
smoothed immediately with the hand squeegees before the emulsion breaks. Longitudinal joints shall be
overlapped no more than 6 inches over previously placed slurry. Slurry seal will be measured and paid for by
the square yard of street surface properly sealed and accepted by the Engineer. Building paper shall be used at
transverse joints to minimize or eliminate overlap. When drags are used, they must be kept clean and free of
build-up. Joints shall be straight and have a neat appearance.
3. Hand Work
Approved hand squeegees with burlap drags shall be used to spread slurry in areas not accessible to the slurry
mixer. Care shall be exercised as to the specified application rate and workmanship, as to leave no unsightly
appearance from hand work..
4. Mix Stability
The mixture shall possess sufficient stability so that premature breaking of the material in the spreader box does
not occur. The mixture shall be homogeneous during and following mixing and spreading, it shall be free of
excess water or emulsion and free of segregation of the emulsion and aggregate fines from the coarser
aggregate. Spraying of additional water into the spreader box will not be permitted.
5. Lines
Care shall be taken to ensure straight lines along curbs, shoulders and joints. No runoff on these areas will be
permitted. Lines at intersections will be kept straight to provide a neat appearance.
6. Curing
Slurry treated areas shall be allowed to cure until such time as the Engineer permits their opening to traffic. The
slurry seal mixture shall be proportioned to permit traffic on the newly sealed surface within 1 to 4 hours of
placement. The Contractor shall protect the area with suitable barricades for the full curing period, per the
approved traffic control plan.
7. Rolling
Slurry seal placed on parking lots, alleys, cul-de-sacs or low traffic volume areas, as determined by the
Engineer, shall be rolled with a pneumatic tire roller with a minimum weight of four (4) tons. Rolling shall start
when the slurry seal has set sufficiently to prevent any pick-up of material and rolled a minimum of three (3)
coverages by the roller until a uniform surface is obtained. Payment for rolling will not be measured or paid for
separately, but shall be included in the unit price for Slurry Seal.
8. Maintaining Traffic
The seal coat shall be applied to alternating streets to provide sufficient public parking for those residents living
on streets which have been closed. Traffic will not be allowed on the newly placed bituminous material until, in
the opinion of the Engineer, the bituminous material has sufficiently set and bonded to prevent damage by
vehicular traffic. Areas which are subject to an increased rate of sharp turning vehicles may require additional
time to allow for a more complete cure of the slurry seal mat to prevent damage. Street closures shall be opened
as soon as the material has sufficiently set and bonded.

collected on a daily basis, removed from the site, and disposed of to a site approved by the Engineer.
All applied slurry surfaces shall be swept by an approved sweeper to remove any excess raveled material which
becomes dislodged from the street surface after five (5) days. Dislodged material from the street shall be
disposed of to a site approved by the Engineer. Payment for sweeping shall be paid for separately as described
in Section 02000 "Revision of Section 105; Maintenance During Construction". Excessive raveling, as
determined by the Engineer, shall be swept by the Contractor at no additional cost to the Owner.
QUALITY CONTROL
The Engineer may use the recorders and measuring facilities of the unit(s) to determine application rates,
asphalt emulsion content, mineral filler and additive. Yield estimates with supporting documentation from the
metering devices and material delivery tickets will be provided by the Contractor on a daily basis.
1. Materials
The Contractor will supply the Engineer with samples of the aggregate and asphalt emulsion used in the project
at the Engineer's discretion. Gradation and sand equivalent tests may be run on the aggregate and (residual
asphalt) content tests on the emulsion. Test results will be compared to specifications. The Owner must notify
the Contractor immediately if any test fails to meet the specifications.
2. Slurry Seal
Samples of the material may be taken directly from the mixing unit(s). Consistency and residual asphalt content
tests may be made on the samples and compared to the specifications. Costs will be computed in accordance
with Section 01400 "Quality Control". The Owner must notify the Contractor immediately if any test fails to
meet specifications. The calibration of the slurry mixing unit will be periodically checked as discussed under
"Equipment; Calibration".
