in accordance with the manufacturer. Size of rubber particles shall be
between a minimum 1 mm 1/32 inch, and a maximum 3 mm 1/8 inch diameter.
Binder shall be between a minimum 16 percent and a maximum 21 percent total
weight of rubber used in the wear surface, and shall provide 100 percent
coating of the particles. Wear surface shall be a minimum 10 mm 3/8 inch
thick. The wear surface shall be porous.
2.2.3.2
Synthetic Turf Wear Surface
Synthetic turf wear surface shall consist of nylon fibers a minimum 500
denier, or heavy face weight polypropylene fiber a minimum 5,000 denier;
and tufted construction conforming to ASTM F 1015. Fibers in each roll
shall be from the same dye lot.
2.2.3.3
Rubber Sheet Wear Surface
Rubber sheet wear surface shall consist of a smooth, uniform formulation of
EPDM rubber granules bonded under pressure in the factory with polyurethane
to form a continuous sheet, and shall be a minimum 10 mm 3/8 inch thick.
Up to a maximum 80 percent of the rubber may consist of SBR particles.
Particle size shall vary from a minimum 1 mm 1/32 inch to a maximum 5 mm
3/16 inch diameter.
2.2.3.4
Polyethylene Plastic Woven Sheet Wear Surface
Polyethylene plastic woven sheet wear surface shall be lockstitched and
meet the tear resistance test, ASTM D 2261 and shall have an accelerated
ultra-violet degradation protection feature.
2.2.4
Synthetic Tile
Synthetic tile shall be sized [as indicated] [_____]. Synthetic tile shall
be a factory-molded unit consisting of the following: combining impact
attenuating substrate and wear surface meeting requirements specified for
substrate and wear surface; or a dual-density, uniform material, the top
portion of which shall conform to wear surface requirements specified.
2.2.5
Color
**************************************************************************
NOTE: Specify the percentage of each color granule
for a unified poured-in-place system. Recommend the
overall color of the surfacing be light colors to
reduce contact burn risk from solar heat buildup.
An EPDM wear surface is preferred for color
retention.
**************************************************************************
The color shall be [as shown in Section 09915 COLOR SCHEDULE] [as
indicated] [_____]. An EPDM wear surface is preferred for color retention.
Black or the following dark colored SBR wear surfaces retain heat and are
not acceptable: color combinations containing more than 10 percent black;
or color combinations averaging more than 10 percent dark colors.
2.2.6
Sealant
Sealant for tile or combined protective surface systems shall be compatible
with the protective surfacing, and shall match the color of the wear
surface.
