PAVED IN PLACE POLYURETHANE TRACK SURFACE BLACK MAT
1. PURPOSE:
The intent of this specification is to provide a guideline for the
improvement of a previously sound bituminous concrete sub-base. Action Track
100 is a mixture of uniformly graded black EDPM rubber granules bound with 100%
polyurethane binder. This system is a pervious all weather surface extremely
durable, resilient and self-sealing.
2. SCOPE:
The work covered by this specification consists of furnishings all labor,
equipment materials, and performance of all operations in connection with the
installation of the surface on track and field events.
3. STANDARD OF QUALITY:
The standard of Quality for the Synthetic Track Surface shall be “Action Track
100” as manufactured by Nagle Seal Coating Inc. in Liverpool, New York at (315)
622-1313.
4. CONTRACTOR QUALIFICATIONS:
Contractors must show evidence of at least five surface installations in the
last three years utilizing the exact system specified. Contractors wishing to
be considered as an “or equal” must provide documenta- tion for their products
twelve days prior to the bid opening. Information shall include the following:
A complete list of references with project name and contacts, with phone
numbers, for each equal installation, or approved equal surface.
5. MATERIALS:
• Action Track Polyurethane Primer.
• EPDM Rubber Base Mat Granulate, 1mm to 3mm or 1mm to 4mm rubber containing no
dust.
• Clear, 100% polyurethane base mat binding agent.
• Action Track line marking paint.
6. SURFACE PREPARATION:
•After a suitable soil sterilant, a recommended bottom course shall consist of
4” to 8” of compacted crushed stone, gravel, or suitable aggregate over a firm,
stable frost free sub-grade which has been brought to proper contour and
elevation in strict accordance with drawings and/or specifications, and
compacted to 95% density.
•A binder-leveling course of an open-textured bituminous concrete (maximum
stone size of ¾”) is laid upon the pre-pared bottom course to a compacted
thickness of 1.5”.
•The wearing (top) bituminous concrete course consists of 3/8” maximum
aggregate to a thickness of 1” compacted.
7. PLANARITY AND SLOPE:
Before the application of the surface course, the asphalt base should be tested
for planarity using a 10’ straight edge. All leveling work should be performed
so that the finished surface slope is a minimum of 1%. Low spots to be
rectified prior to installation of base mat.
8. PROCEDURE:
•Following inspection of asphalt base and required curing time, the entire area
to be surfaced shall be thoroughly cleaned, removing any foreign and loose
material.
•Action Track Polyurethane Primer will then be applied to the entire surface
uniformly at a rate of not less than .3 lbs. per square yard. Allowing a
minimum of 30 minutes curing time before the application of the base mat
material.
•The base mat will consist of an 18 to 23% range polyurethane base mat binding
agent and 77 to 82% range EPDM rubber base mat granulate as described above.
This mixture is prepared in a mechanical mixer or suitable continuous mixer
which is clean and dry. The base mat is applied with mechanically operated
screed machine which has an electrically heated screed. All joint work will be
flush with the adjacent mat. Joints which have cured will have their edges
primed with Action Track Polyurethane Primer.
9. WARRANTY:
Five (5) years from the completion date.

to the recommendations of Nagle Seal Coating Inc. and/or in accordance with the
drawings and specifications of the architect or engineer and/or in accordance
with N.F.H.S.A., I.A.A.F. regulations. The line paint to be used shall be
compatible with polyurethane surface as recommended by Nagle Seal Coating, Inc.
