Contractor will be reimbursed on a separated line on invoice in one lump sum on each
individual invoice. The Contractor will not be reimbursed for any police detail expenses

2. The unit of measure will be determined by the awarding authority and set forth in the proposal
documents. Payment shall be at the unit price bid in the proposal and shall be full
compensation for furnishing, preparing, placing the material specified and furnishing of all
labor, equipment and incidentals for the satisfactory completion of this item. The unit of
measure may be any of the following:
a. Gallon
b. Pound
c. Linear Foot
d. Square Yard
e. Day
f. Lump Sum
3. Crack sealant shall be a (PCRM) hot-applied modified asphalt-fiber compound designed
specifically for improving the strength and performance of the parent asphalt sealant.
a) The asphalt binder shall consist of a blend of neat asphalt binder, chemically modified
crumb rubber (CMCR), and a polymer package, all of which meet the following
specifications:
1) The binder will meet PG 64-28E requirements after modification including:
▪ PG grade requirements of AASHTO M320
▪ Requirements of AASHTO TP70/MP19
2) Modification, at a minimum, shall consist of 7% crumb rubber, and the maximum
particle size for the recycled tire rubber shall be 80 mesh (#80 sieve)
3) The asphalt supplier shall provide testing for both the neat and modified asphalt
binders
4) See below for typical modified test results for 64-28E with crumb rubber:
DSR ORIGINAL
• kPa >1.00 @ 64 C. Fail temp = 76+ C
DSR RTFO
• kPa >2.20 @ 64 C. Fail temp = 76+ C
MSCR
• JNR (MSCR unit of measure): 3.2 E <0.5% @ 64 C
• R3200 (Average % Recovery): >70%
DSR PAV
• kPa <6000 @ 64 C
BBR
• Stiffness <300 @ -18 C. M-Value >0.300 @ -18
b) The fiber reinforcing materials shall be short-length polyester fibers having the
following properties:

Elongation at Break (ASTM D2256-90)
Melting Point (ASTM D3418-82)
Crimps/Inch (ASTM D3937-90)

* At temperatures ranging from ambient to maximum finished product mix
temperature
** Subject to Normal Variations
c) Modifying Compound: The modified asphalt-fiber compound shall be mixed at a rate
of 6-8% fiber weight to weight of asphalt cement. This compound having the same
chemical base provides compatibility and exhibits excellent bond strengths. The fiber
functions to re-distribute high stress and strain concentrations that are imposed on the
sealant by thermal sources, traffic loading, etc.
4. Equipment used in the performance of the work required by this section of the specification
shall be subject to approval by the Owner and maintained in a satisfactory working
condition at all times.
Air Compressor: Air compressors shall be capable of furnishing not less than 100 cubic
feet of air per minute at not less than 90 lbs. per square inch pressure at the nozzle. The
compressor shall be equipped with traps that will maintain the compressed air free of oil
and water.
Broom or Sweeper: Manually operated, gas powered air-broom or self-propelled
sweeper designed especially for use in cleaning highway and airfield pavements shall be
used to remove debris, dirt and dust from the cracks.
Melter: The unit used to melt or maintain the crack sealant compound at the
recommended application temperature shall be the indirect fired type. It shall be equipped
with a remote heat exchanger and hot oil circulation pump capable of maintaining a
consistent temperature of the heat transfer oil. The heat transfer oil shall be circulated to
all sides and the bottom of the vat containing the crack sealant compound making a
continuous loop back to the heat exchanger and having a flash point of not less than
600F. The melter shall be equipped with a satisfactory means of agitating the crack
sealant at all times. This may be accomplished by continuous stirring with mechanically
operated paddles and/or by a circulating gear pump attached to the melter. The melter
must be equipped with a thermostatic control calibrated between 200F and 550F and
must be capable of pumping an 8% fiber content blend.
