shall be removed from the pavement by approved methods and discarded. Any
workmanship determined to be below the high standards of the particular craft
involved will not be accepted, and will be corrected and/or replaced as
required by the engineer in charge.
8. Performance:
It is the intentions of the Public Agency not to award a contract for this work
under this or any other proposal if the bidder cannot furnish satisfactory
evidence that he has the ability and experience to perform this class of work
and that he has sufficient capital and equipment to enable him to prosecute the
work successfully and to complete it within the time named proposal or to award
the contract as is deemed to be the best interest of said Public Agency. The
contractor must submit with his bid proposal a list of six (6) jobs which he
has successfully completed, giving the name and the address of these projects
so they can be investigated prior to the award of the contract.
9. Sampling and Testing:
Joint sealer will be tested for conformance with Federal Specification SS-S-164
or 140 lb. joint material sample shall be submitted for approval prior to start
of the work. Manufacturing certificates that joint sealer meets Federal
Specification listed above will be accepted by the engineer, unless otherwise
stated in specification proposals.

DETAILED ONE-COAT APPLICATION
1. PURPOSE:
The intent of this specification is to provide a guideline for the
preservation and improvement of a previously prepared sound, bituminous
concrete pavement. This surface treatment shall consist of one (1) applied coat
of Action Pave rubberized coal tar pitch emulsion. The coat is to be fortified
with mineral aggregate to form a sand slurry coat. This coating will protect
the pavement from the deleterious effects of fuel spillage, salts, weather and
oxidation.
2. SCOPE:
The work covered by this specification consists of furnishing all labor,
equipment and materials and performance of all operations in connection with
the application of rubberized coal tar pitch emulsion slurry sealcoat on
bituminous, pavements, complete, in strict accordance with these specifications
and the applicable drawings and subject to the contract terms.
3. Materials:
• Rubberized coal-tar pitch emulsion-shall be Action Pave as manufactured by
Copeland Coating Company, Inc., Albany, NY, as outlined in Action Pave Product
Specification. The rubberization shall take place prior to emulsification of
the finished product. The oil-resistant rubber shall be blended with the hot
refined coal tar base.
• The rubberized coal-tar emulsion shall be prepared for a refined tar, high
temperature, coal-tar pitch (R-11 or harder)meeting or exceeding the
requirements of Federal Specification RT-143. Oil and water gas tars shall be
excluded. Under no circumstances will there be allowed the addition of carbon
black or lamp black to enhance the color of the material.
• The contractor shall be prepared to show certification that the product to be
delivered and applied is Action Pave and that said product complies with
Federal Specification RP-355d and the specifications of this contract.
• Mineral aggregate shall be added at a rate of 3 to 6 lbs./gal. ratioed to the
undiluted Action Pave. The mineral aggregate shall be clean, dry, hard,
durable, evenly graded silica sand. This sand will have a sieve gradation
rating of 45 to 85. Sand gradations may very according to local availability
and field conditions.
• Water used for blending the slurry mix and for rinsing or wetting the
pavement surface shall be clean, potable and carefully measured to obtain
job-specific slurry mixes.
4. Surface Preparation:
• The pavement surface to be coated must be properly designed, structurally
sound, surface cured and free of oil, grease, vegetation and other deleterious
materials. The surface must demonstrate "Coatability" evidenced by becoming
thoroughly wetted when a quantity a clean water is splashed on the surface
where it must sheet, and wet the surface uniformly without showing oily rings.
• Surface cleaning equipment can include motorized sweepers, water flushing
equipment, power blowers, and compressors along with hand brooms, shovels,
etc., to be employed in those areas inaccessible to power equipment.
• All vegetation shall be removed from surfaces to be coated. Where necessary,
sterilization to prevent re-growth shall be accomplished by the application of
herbicide or by burning with a propane torch.
• Petroleum stains and oil spots shall be cleaned by scraping or wire brushing
the area and/or lightly burning off the area with a propane torch to remove
volatiles. The areas thus prepared shall be coated with Oil Spot Primer as
manufactured by Copeland Coating Company, Inc., Albany, NY, in accordance with
the manufacturer's instruction. Apply by brush, allow to dry thoroughly before
applying coal-tar sealer.
• Just prior to application of the first coat of Action Pave, the surface to be
coated, in addition to the above-listed preparations, shall be blown clean of
all remaining loose dust, stones, etc., by means of compressor, air broom, or
power blower that is capable of directing a wind velocity of not less than 100
m.p.h. directly across the pavement surface. Brooms or other hand tools may be
sued to facilitate this final cleaning process.
The following preparation should be done prior to seal coating at an additional
cost to the owner:
• Cracks of 1/8" and wider shall be cleaned and filled in accordance with the
standard approved method as is necessary for the application of crack-filling
materials meeting Federal Specifications SS-S-1401B or SS-S-164. Routing may be
required.
• Patching of areas determined to be in need of repair: potholes, alligator
cracks, petroleum softened areas, etc., shall be completed at least 15 days
prior to actual application of sealcoat so that the patched areas will have
proper time to cure.
5. Application of Sealcoat Material:
• When the prepared surface and the rubberized coal-tar pitch emulsion sand
slurry have been inspected and approved, apply one (1) coat of Action Pave sand
slurry. • Action Pave shall be applied in a uniform manner over the entire
prepared pavement surface. The Action Pave shall be applied in such a manner
that it provides a continuous, adherent coating with no holiday, voids, or
pinholes. Areas previously treated with Oil Spot Primer, and those patched or
repaired shall be inspected and "touched up" if necessary, along with any
holidays or pinholes prior to the application of the second coat of Action
Pave.
• Action Pave shall be applied at a minimum coverage rate of 0.10 gallon per
square yard per coat.
• Action Pave shall be applied only under good drying conditions, i.e. ambient
air and pavement temperatures of 40* F and rising must be present. A relative
humidity near 50% accompanied by a breeze and 75* F temperatures with no rain
eminent comprise ideal coating conditions. The application of Action Pave under
conditions other than the above is at the contractor's discretion, and it is
his responsibility to ensure the Action Pave has dried to rain-resistant
condition before the ambient temperature is below 40* F or the occurrence of
any precipitation. It is the contractor's responsibility that no Action Pave
enters the storm drainage system, either during application or as surface
run-off, should rain occur.
• The first coat of Action Pave shall be thoroughly dry and tack-free prior to
the application of the second coat. The second coat should be applied
immediately over the first, with not traffic or contamination of the first coat
being allowed. The second coat should be allowed to dry and cure for a minimum
of 10 hours under good drying conditions before being returned to traffic.
6. Method of Application:
• The mixing/applicator machines shall be a self-propelled, pneumatic-tired
vehicle capable of applying the combined sand sealer slurry as required by this
specification. The agitation system shall be such that the combined slurry
mixture shall remain in constant agitation without the possibility of foaming
or entraining any air. The spray or squeegee application device shall be
capable of providing a smooth, adherent, uniformly coated surface. There will
be easy access to the mixing vessel at all times to allow accurate measurement
of emulsion, aggregate, and water, if necessary, into the vessel.
7. Clean-up:
• The contractor shall remove from the site within 24 hours of completion all
job-related tools, equipment, barricades, and job debris unless previous
arrangements have been made with the owner.
8. Pavement Marking:
• Where pavement marking is required, the sealcoat should be thoroughly dry.
Striping layouts shall comply with all local, state and federal requirements.
