MATERIALS - GENERAL REQUIREMENTS
1.
Type of Asphaltic Oil for Tack coat
Tack coat required under this project shall be SS -1H.
Water used to dilute emulsified asphalt shall be mixed in
approximate 50-50 proportion with the oil. The rate of
application of the diluted emulsified asphalt shall
generally be from .10 to .20 of a gallon per square yard.
2. Asphaltic Concrete
Type 17 C asphalt according to the 1997 Standard State
Specifications and its supplements.
3. Payment shall be made per ton asphalt and shall include all
installation costs including, but not limited to sweeping and
base preparation not otherwise provided for by separate
pay item.
NOTE: Contractor will take extra care to protect all survey markers,
located in street, during construction.
NOTE: Care will be taken to salvage existing manhole rings
and covers and keep sets matched together.
NOTE: Where pavement is milled, apply courses
as specified to thickness as outlined on the
plans or as specified in field by Engineer.
NOTE: Salvage subbase in areas as specified
on plans or as directed in field by Engineer.
ASPHALT PAVEMENT SPEC. SHEET
Laying, compacting and finishing shall be in accordance with sections
503 and 1028 of the 2007 Standard State Specifications and its supplements.
Flagging and temporary traffic control for construction will not be paid
for directly, but will be subsidiary to the contract.
CONTRACTOR'S NOTE
1. Payment will be made for actual field quantities utilized and
shall show precedence over contract estimated quantities.
2. Locations of all manholes and valves will be tied off and recorded
prior to any work. Manholes will be kept covered and kept clean
throughout all of resurfacing project.
3. All drives and approaches will be asphalted back, as directed by
Engineer in field.
4. It will be the responsibility of the Contractor to dispose all
pavement removal.
5. Any earth excavation will be disposed of on-site
on adjacent lots.
6. Contractor will be required to notify property owners a minimum of
24 hours prior to any work being started, so cars, etc. can be moved.
7. Contractor will lay new asphalt surface in a two lift process.
Unless otherwise specified by plans or Engineer.
8. Contractor will be required to have all utilities located prior to
start of work.
NOTES:
The embankment and subgrade shall be adjusted to conform to the lines and
grades on the plans in accordance with Section 205 and 302 of the 2007
Standard State Specifications and its supplements. The upper six (6) inches of
the subgrade shall be scarified, mixed and recompacted to the following
compaction requirements:
Percent Density Moisture Minimum Requirements Maximum
95 Min. Opt. -3% Opt. +3%
Areas not meeting specified moisture density test requirements shall be
removed and recompacted at the Contractor's expense.
All subgrade compaction and water necessary for subgrade construction
shall not be paid for directly but shall be considered subsidiary to the
items of the contract.
Excavation, backfilling, and sawing control joints, keyway, tie bars,
dowel pins, and rubberized joint sealant shall be considered subsidiary
to the unit price per square yard of pavement.

ASPHALTIC CONCRETE, TYPE 17C w/.40 CRUSHED
Asphaltic Concrete, Type 17C , shall conform to the AASHTO T245 test for a
50 blow mix criteria.
Subsection 1007.01 in the 1997 Standard Specifications is amended to include
Asphaltic Concrete, Type 17C.
The combined mineral aggregate for Asphaltic Concrete, Type 17C, shall
have a minimum crushed value of 40 percent. The crushed value for mineral
aggregates shall follow the Special Provision, "CRUSHED AGGREGATE FOR
ASPHALTIC CONCRETE". Of the combined mineral aggregate not more than
60 percent can be limestone. The target field air void shall be 3.5 percent.
The gradation of the combined aggregates shall be such that a job mix
formula meeting the gradation requirements shown below can be established.

The percent design target air void shall equal the field target plus one
percent. Field control target air voids shall consist of a maximum equal to the
target plus one percent and a minimum equal to the target minus one percent,
based on the moving average of four tests. The minimum percent voids in
mineral aggregates, (VMA) shall have a lab design of ** and field control value
of **. The dust/ac ratio shall have a maximum (lab design) value of 1.2 and a
maximum (cold feed) value of 1.4.

Notes:
Brick paving base (9th -12th Streets) and concrete sub—base (12th -14th Streets) may
require various patching to be determined by Engineer after milling operation and
street has been cleaned.
Millings shall become the property of the contractor.
Ends and returns on Project will be sawed prior to installation of Base Lift.
Some Driveways on this project have asphalt and concrete patched into the gutterline.
Contractor shall use caution not to damage driveways during the removal of this
material.
Contractor shall use care in maneuvering heavy equipment over and around this
Project. Existing curb and gutters are in poor condition. Brick and concrete base
materials will not withstand a lot of weight. If use of milling equipment will damage
existing brick base, contractor may be required to use motor grader and and front
end loader to remove asphalt surfacing.
Inlays required shall be subsidiary to rotomill pavement.
