The warranted hot mix asphalt shall be a mixture of aggregate, filler or additives if used,
bituminous material, hydrated lime, and reclaimed material if used. A minimum of one percent
hydrated lime by weight of the combined aggregate shall be added to the aggregate for all
warranted hot mix asphalt.
The Contractor shall establish the materials mix design (MMD) for the hot mix asphalt. The MMD
consists of an aggregate gradation based on percentages of the material passing various sieve sizes, a
percentage by weight of bituminous material to be added to the aggregate, and a temperature for the
mixture at discharge from the mixing plant. The Contractor shall select all materials to be used in the
mixture including the asphalt cement. Transverse cracking shall not be included in the performance
warranty if the asphalt cement meets or exceeds the low temperature required for Superpave
performance grade PG 64-28 conforming to subsection 702.01.
The minimum thickness placed shall be as shown on the plans.
Two weeks before starting paving, the Contractor shall provide the Engineer the MMD, the method of
developing the MMD, all MMD testing, a list of materials, and all thickness testing methods.
The hot mix asphalt shall be warranted for 2 years against the types of distress listed in (d) below.
(a) Warranty and Warranty Bond. By submission of its bid in response to this specification, the
Contractor warrants that all of the hot mix asphalt placed on the project shall be free of defective
materials and workmanship for a period of 2 years from the date of pavement acceptance as
defined in the Revision of Section Acceptance.
The Contractor further warrants that it will ensure proper and prompt performance and
completion of warranty work in accordance with this specification. Warranty work shall be
performed when any defect occurs in the hot mix asphalt materials or workmanship within that 2

Page 9 of 31
completion of warranty work includes payment for all labor performed and for all equipment and
materials used.
All such warranty work shall be solely at the Contractor’s expense up to $50,000. The City may
elect to have additional work performed and will be responsible for payment of actual expenses
incurred by the Contractor. Additional work shall be authorized in writing by the Engineer. All
documentation of actual costs incurred in the performance of warranty work shall be made
available for audit by the City.
The Contractor shall provide a warranty performance bond ("warranty bond") to guarantee the full
performance of the warranty work described in this specification. The warranty bond shall be in
the amount of $50,000.
The warranty bond shall be a single term 2 year (plus an additional nine months in certain
circumstances) warranty bond that will be in effect for the entire warranty period. The warranty
bond shall be in effect upon pavement acceptance, and it shall remain in effect for the total of 2
years from that date. The Contractor shall provide a 2 year warranty bond that fully complies
with this specification to the Department at the time of execution of the Contract.
The need for warranty work, and the performance of that warranty work, shall be determined in
accordance with (d) below. The Contractor will be released from further warranty work at the
end of the warranty period or upon completion of any delay warranty work, as described above,
whichever is later, provided all required warranty work has been satisfactorily completed.
(b) Pavement Evaluation Team (PET). The PET shall have the final decision authority for all warranty
work. The PET shall consist of three subject matter experts not affiliated with the project. One
member will be a City of Fort Collins staff person, the second member will represent the asphalt
paving industry, and the third will be mutually agreed upon by the other two members. Each
member of the PET shall have a minimum 15 years experience in one or a combination of the
following disciplines: pavement management, asphalt pavement design, asphalt pavement
construction, maintenance management or asphalt pavement maintenance. The City will cover
expenses associated with performing the duties of the PET for the City member and the mutually
agreed upon third party. The Contractor shall cover expenses associated with performing the duties
of the PET for the asphalt paving industry member
Members will be replaced as necessary based upon the criteria above.
The City representative on the PET shall be responsible for scheduling distress surveys, preparing
the reports, and notifying the Engineer when warranty work is required.
(c) Warranty Work. During the warranty period the warranty work shall be performed at no cost to the
City and shall be based on the results of the pavement distress survey. Warranty work to be
performed and materials to be used shall be in accordance with the remedial actions and other
requirements in (d). The Contractor may propose alternative actions for warranty work to the
Engineer who will submit the proposal to the PET. All warranty work to repair distresses shall be
done in accordance with the project specifications and plans and current City of Fort Collins and
CDOT standards and coordinated with the Engineer. Innovative materials and techniques may be
considered. The PET will render a final decision by majority vote.
Addendum 1
8125 Intersection Improvements at Vine & Shields
Page 10 of 31
During the warranty period, the Contractor may monitor the pavement in question using
nondestructive procedures. All proposed remedial actions shall be coordinated with the Engineer.
Coring, milling or other destructive procedures shall not be performed by the Contractor without
prior written consent of the Engineer. The Contractor is not responsible for damages that are a
result of coring, milling or other destructive procedures conducted by the City, utility companies
or other entities not under the control of the Contractor.
When notified by the PET that warranty work is required, the Engineer will notify the Contractor
and Surety, in writing. If the Contractor or Surety fails to respond in writing within fifteen days
after receiving written notice from the Engineer, the City may make repairs or contract to have the
repairs made and the Contractor and surety shall be responsible for the total cost of these repairs
including lane rental fees.
At least 30 days before the expiration of the warranty, and at any other time during the warranty
period as deemed necessary by the Engineer, the PET shall conduct a pavement distress survey. If
the Engineer is notified by the PET that warranty work is required in accordance with the distress
indicators, the Engineer will notify the Contractor and surety in writing. If the Contractor or the
Surety fails to respond in writing within 15 days after receiving written notice from the Engineer,
the City will complete the repairs or contract to have the repairs completed and the Contractor and
Surety shall be responsible for the total cost of these repairs including the lane rental fees. If it is
necessary to delay performance of the final warranty work due to weather limitations or other
reasons in the public interest, the Contractor and City shall agree to the extent of work to be
performed. Any additional distress resulting from the delay will be the responsibility of the
Department.
Warranty work that requires a resurfacing of the pavement shall be performed only when
weather conditions are in accordance with subsection 401.07.
The Contractor shall maintain traffic at all times as detailed in the Traffic Control Plan. Warranty
work shall be performed during the times of day and days of week specified for the original
contract work.
(d) Pavement Distress Indicators, Thresholds and Remedial Action. Pavement distress indicators
shown below shall be used as the basis for determining the distress types to be considered for repair
under the warranty and as the basis for determining the methods for measuring distresses.
The pavement distress surveys are conducted by dividing the roadway into nominal one-mile
sections. A one-tenth mile segment in each mile will be evaluated for pavement distress. The
segment evaluated shall be from 0.3 to 0.4 miles from the start of the section. In addition, in each
section, a random one-tenth mile segment will be surveyed. The random one-tenth mile segments
will be determined by the PET each time a survey is conducted.
The PET will conduct intermediate surveys if requested in writing by the Engineer. The PET will
notify the Engineer in writing of the survey results within 15 days. The Engineer will immediately
notify the Contractor in writing. Traffic control for conducting the surveys will be the
responsibility of the Department.
Addendum 1
8125 Intersection Improvements at Vine & Shields
Page 11 of 31
If any survey requires remedial action and the Contractor does not dispute the survey results, the
Contractor shall remedy the distress. If the survey requires remedial action and the Contractor
disputes the survey results, the Contractor shall notify the Engineer in writing within 15 days of
receiving notice. The notification shall describe the contractual and legal basis for the
disagreement with the survey results. The Engineer will transmit the Contractor's notification to
the PET which will render a final decision and notify the Engineer in writing within 30 days of
the Contractor's notification.
The PET shall determine the remedial action to be performed in all segments in the project where
the threshold level is met or exceeded. If areas outside the survey segments are suspected of
meeting or exceeding a threshold level, the PET will divide the entire project into 0.1 mile
segments and conduct the distress survey in any, or all, segments to see if a threshold level has been
met or exceeded. Unless otherwise directed by the Engineer remedial action shall be performed in
the same calendar year as the survey that indicated the threshold level is met or exceeded.
Remedial action shall be applied to each entire segment in which the threshold level is met or
exceeded unless otherwise noted under remedial action. When the remedial action required
includes an overlay, the action shall also be performed on the hot mix asphalt shoulders and
adjacent lanes.
If remedial action necessitates a corrective action to the pavement markings, adjacent lanes or
roadway shoulders, then such corrective action to the pavement markings, adjacent lanes and
shoulders shall be performed at the expense of the Contractor.
When remedial action requires the removal of pavement, the pavement shall be replaced with a
mix approved by the PET. The mix shall be placed according to the Contractor's QCP. Pavement
shall be removed by cutting neat lines vertically for the full depth of the affected layer unless
otherwise specified. Removal areas shall be rectangular, and the sides and bottoms shall be
thoroughly coated with an approved tack coat prior to pavement replacement.
If, anytime during the warranty period, 30 percent or more of the project segments require or have
received remedial action, then the entire project shall receive a remedial action as determined by
the PET.
The Contractor will not be held responsible for distresses which are caused by factors beyond the
control of the Contractor. A finding that the distress is due to factors outside the control of the
Contractor shall be based on evidence submitted by the Contractor to the Engineer. The PET will
make the final determination.
Distress types to be warranted, the threshold levels requiring remedial action, and the
remedial action to be performed by the Contractor shall be according to the following
pavement distress indicators:
1. Permanent Deformation - Rutting and Shoving. Rutting is longitudinal surface depression in
the wheel path. Shoving is longitudinal displacement of a localized area of the pavement
surface caused by traffic pushing against the pavement. Rutting shall be measured at 50 foot
intervals using a 6 foot straight edge, and taking several measurements transversely across
the pavement to determine the maximum rut depth. Rut depths shall be rounded to the
nearest
0.10 inch.

If the rutting is suspected to be caused by the base or subgrade, coring (or cross
sectional sampling) will be conducted by the Department to determine the cause
of the rutting. The Contractor shall have the option to obtain cores and cross-
section samples at his own expense, including repair of the sampled areas, and
traffic control.

6. Delamination of Pavement Layers. Delamination of pavement is the separation of one layer from
the layer below it.
Remedial action for delamination: affected area shall be removed and replaced to one foot
beyond the apparent distress.
7. Transverse Cracking. Transverse cracks are cracks relatively perpendicular to the pavement
centerline. The highest severity level present for at least 10% of the total length of the crack shall be
assigned. Random cracks with transverse cracks are cracks that occur randomly and are within two
feet of the transverse crack. Since the top mat of asphalt pavement will be placed over Portland
Cement Concrete Pavement, transverse cracks determined to be caused by existing joints in the
concrete pavement will not be included as part of the warranty. Spalling with transverse cracks is
the cracking, breaking or chipping of the pavement surface within two feet of the transverse crack.
