median hardscaped areas.
Median Splash Block/Hardscape Shaping (Complete in Place) — The areas in the medians beneath the
exposed aggregate concrete shall be backfilled with suitable onsite material approved by the Engineer. These
areas shall be backfilled in lifts not to exceed 6 inches (6") and compacted with a plate compactor or as

moisture. Maximum density shall be determined by ASTM D 698. This will apply under the roadway, curb and
gutter, sidewalk, and driveways. Topsoil shall be compacted to 85% of maximum density at/or near optimum
moisture.
Excavation and Embankment will only be paid when a significant change in grade is required, as determined
by the Engineer. Minor cuts and fills shall be considered incidental to the work, and shall not be paid

Those areas which produce a rut depth of over one-half (1/2) inch or which crack the subgrade after pumping
and rebounding shall be ripped, scarified, wetted or dried if necessary, and recompacted to the requirements
for density and moisture at the Contractor's expense. Where unsuitable material is encountered, the Engineer
may require the Contractor to remove the unsuitable materials and backfill to the finished grade with approved
material. The completed subgrade shall be proof -rolled again after placement of approved material. This will
be paid for at the contract unit price for Muck Excavation.

REVISION OF SECTION 206
EXCAVATION AND BACKFILL FOR STRUCTURES
Section 206 of the Standard Specifications is hereby revised as follows:
Subsection 206.03 is revised to include the following:
Structure Excavation — It is anticipated that unsuitable soils will be encountered for the foundation of the box
culvert. The excavation of the unsuitable material has already been accounted for and will be paid for under
the Muck Excavation item.
The Contractor is cautioned that construction equipment may cause the natural soils to pump or deform while
performing excavation work inside and on footings, structural floor slabs, or other structure foundation areas.
Foundation materials which are: a) saturated by either surface or dewatering work by the Contractor; b) frozen
for any reason; or, c) that are disturbed by the Contractor's work or caused to become unacceptable for
foundation material purposes by means of the Contractor's equipment, manpower, or methods of work shall be
removed and replaced by the Contractor at his expense.
Care should be taken when excavating the foundations to avoid disturbing the supporting materials.
Excavation by either hand or careful backhoe soil removal, may be required in excavating the last few inches
of material to obtain the subgrade of any item of the concrete work.
Any over -excavated subgrades that are due to the Contractor's actions, shall be brought back to subgrade
elevations by the Contractor and at his expense in the following manner:
1. For over -excavations of 2 inches or less, either: Backfill and compact with an approved granular
materials; backfill with '/2 inch washed crushed rock; or fill within concrete at the time of the
appurtenant structure concrete pour.
2. For over -excavations greater than 2 inches, backfill and compact with 1 '/z inch washed crushed
rock.
Structural Backfill (On -site Fill) - Backfill, and fill within 2 feet of and adjacent to all structures and for full
height of the walls, shall be selected non -swelling material. It shall be granular, well graded, and free from
stones larger than 3 inches. Material may be job excavated, but selectivity will be required as determined by
the Engineer. Refer to the Plans for job specific requirements. Stockpiled material, other than topsoil from the
excavation shall be used for backfilling unless an impervious structural backfill is specified. The backfill
material shall consist of either clean on -site granular materials free of stones larger than 3 inches in diameter
with no more than 20% passing the No. 200 sieve, or equivalent imported materials. All backfill around the
structures shall be consolidated by mechanical tamping. The material shall be placed in 8-inch loose lifts
within range of 2% above to 2% below the optimum moisture content and compacted to 95% of Maximum
Standard Proctor Density (ASTM D698) for cohesive soils, or to 70% relative density for pervious material as
determined by the relative density of cohesionless soils test, ASTM D4253.
Structural Haul and Leveling - This shall consist of hauling and leveling of any excess material or unsuitable
fill material on site. This item will be measured from the plans and cross sections and will be paid for by the
cubic yard. This item shall be paid according to plan quantity.
Structural Backfill flow fill — Backfill flow fill will be required around the foundation and up to a height of 2'
above the foundation.
0
Dewatering — This item shall include pumps, labor, equipment and any associated costs to insure a dry work
area. Also, a discharge pipe is to be installed and removed to provide access for construction equipment.
These combined items will be paid for as a lump sum price.
Dewatering should not be conducted by pumping from inside footing, structural floor slab, or other structure
foundation limits. This may decrease the supporting capacity of the soils.

material. A copy of the manufacturer's recommendations pertaining to the application of the sealant shall be
submitted to the Engineer for approval prior to the beginning of work, and these recommendations shall be
adhered to by the Contractor, with such exceptions as this specification may require. The sealant material
shall be applied into the joint using equipment and techniques recommended by the joint sealant manufacturer.

accordance with the criteria outlined.
Backer rod: Shall be a round, heat resistant material meeting the requirements set forth by the joint sealant
manufacturer. The Contractor shall submit the proposed material to the Engineer for review and approval prior
