directions necessary for safe passage of traffic around the work site shall be reviewed and changed, if
necessary, to meet the needs of the situation. Signage erected, but not necessary or proper for the situation
ahead shall be covered or taken down. Barricading and signage shall be monitored by the Contractor on a
daily basis to ensure that it meets the requirements for work zone safety in the conditions of the work being
performed.
The Contractor shall be responsible for insuring that all barricades, warning signs, lights and other devices
installed are in place and operating twenty-four (24) hours each day, including Sundays and Holidays during the
time this Contract is in force.
In the event of severe weather conditions, the Contractor will be required to furnish any additional personnel
required to properly maintain all traffic control devices.
This work shall not be paid for separately but shall be considered incidental to the Work.

Moisture Regain @ 70°F (21°F) and 65% RH (typical),
% 0.1
C. Percent Fibers – The fiber-asphalt mixture shall contain a minimum of 8.0% (by
weight) fibers.
D. Heating Temperature – The fiber-apshalt filler shall be heated in the kettle at
temperatures between 255°F and 285°F (124°C and 141°C). The temperature shall
never exceed 290°F (143°C).
2. Pre-Mixed Filler: Fiber-modified asphalt crack filler that is pre-mixed and packaged shall
consist of fibers, asphalt binder, and other modifiers. The filler and its components shall be
accepted on certification from the manufacturer that it meets the following requirements.
A. Asphalt Binder – The asphalt binder shall be PG 64-22.
B. Fibers – The fibers shall be short-cut polyester fibers meeting the properties listed
below:
Property Value
0.25 ±0.02
Length, in. (mm) (6.3±0.5)
Denier 3-6
Crimps None
Tensile Strength, Minimum, psi (Mpa) 70,000 (482)
Specific Gravity (typical) 1.32-1.40

Cone Penetration, Maximum, ASTM D5329 30 mm
Softening Point, ASTM D36 200°F (93°C) min
Maximum Heating Temperature 400°F (204°C)
Minimum Application Temperature 350°F (177°C)
Equipment:
Oil Kettle – The crack filler shall be heated in an oil jacketed double wall kettle equipped with an agitator
(reversing rotary auger action) and separate thermometers for the oil bath and mixing chamber. The unit shall
also be equipped with a reversible hydraulic 2-in. (50-mm) hot asphalt pump and a recirculating pump to
circulate the oil bath. The kettle shall be capable of operating at temperatures between 248°F and 293°F
(120°C and 145°C).
Construction Requirements:
The fiber-asphalt filler shall be applied only when the joints and cracks are dry and free of dirt, vegetation,
debris and loose filler. All joints and cracks to be filled shall be blown clean with an air compressor equipped
with a lance using compressed air. The cleaning operations shall be kept close to the filling operations to
prevent debris from being carried back into the joints and cracks before filling.
The fiber-asphalt filler shall be applied using a pressurized wand delivery system with such devices as
necessary to fill the cracks and form a nominal 0.125 in. (3 mm) thick by 3 in. (75mm) wide overseal band
centered so that the center of the 3 in. (75mm) wide band is within 1 in. (25 mm) of the crack. The fiber-
asphalt shall be applied taking care not to use excessive material in either thickness or location.
The Engineer will determine the extent that fine cracks are filled. Care shall be taken to not place filler on top
of pavement markings, structure frames/lids, and drainage castings.
The ambient temperature during filling shall be above 40°F (4°C) and below 85°F (29°C). The filler must
cure before being opened to traffic. In order to more quickly open the road to traffic, the Contractor may use
fine sand, mineral filler, or Portland cement to dust the filler at no additional cost to the Village.
Any material installed with a fiber content below 8% will be removed and reapplied with a minimum of 8%
by the Contractor at no additional cost to the Village.
Cleaning of cracks will not be paid for separately.
Method of Measurement: Crack filling will be measured for payment in pounds of fiber-asphalt applied.
Basis of Payment: This work will be paid for at the contract unit price per POUND of:
FIBER-MODIFIED ASPHALT CRACK SEALING
which price shall include all costs for furnishing the labor and equipment necessary to remove and dispose of
the asphalt surface in accordance with the Specifications.
Page 35 of 52SP-11 FINE AGGREGATE (FA-6)
This item shall consist of providing and applying to the freshly laid sealant a dusting coat of Fine Aggregate
(FA-6) as directed by the Engineer to prevent tracking. The Contractor shall be responsible for sweeping and
cleaning streets to make sure the street surface is in an acceptable condition after crack filling activities. Upon
request by the Village, all loose fine aggregate shall be removed from the pavement surface by means of
mechanical sweepers or hand broom within 72 hours of application. Removal and sweeping operations
shall be considered incidental to this item and shall not be paid for separately.
Basis of Payment – Sanding of the sealant will be paid for at the contract unit price per TON applied for:
FINE AGGREGATE (FA-6)
which price shall include all costs for furnishing the labor and equipment necessary to remove and dispose of
the asphalt surface in accordance with the Specifications.
