PART 2 - MATERIAL DATA (Continued)
Colors - The color of GT Impax recycled poured rubber surfacing will be indicated on plans.
Owner or owner's representative will be responsible for selecting standard blends. Selection of
either standard color blends or custom color blends must be made at time quotation is being
requested. EPDM/TPV colors are available in 100% black and a variety of colors. Ask your
GameTime representative for available color combinations.
Note: If graphic designs and color transitions are used, they shall be full wear course depth.
Color(s) to be determined by architect. Graphic Templates are the responsibility of the
Architect or owner.
Physical Properties:
Tensile Strength (ASTM D412) 60 PSI, minimum
Elongation at Break (ASTM D412) 140%, minimum
Flammability (ASTM D2859) Pass
Coefficient of Friction (ASTM D204)
Wet 0.9, minimum
Dry 1.0, minimum
Water Permeability 0.4 gal. /sq. yd./sec., minimum
PART 3 - SUB-BASE TYPES & DETAILS:
Sub-base Requirements - The base shall have the specific maximum slope (2%) and shall vary
no more than 1/8” when measured in any direction with a 10° straight edge.
Stone - The density requirement is 90% to 95% compaction with final condition of stone as level
and stable so as not to shift when traveled on or during surface installation process. A
compaction test is required and must be submitted to GameTime prior to installation of poured
rubber surfacing. Failure to provide proof of compaction test will void 5-year warranty of PIP
surfacing should signs of sub-base failure occurs.
Depth: 4 inch minimum thickness.
Slope: Stone elevation shall maintain %” per foot toward low end.
Porosity: Base course shall maintain porosity for direct drainage.
Enclosure: Stone base course must be surrounded by a retaining curb.
Drainage: Subsurface drainage is recommended under and around a stone base.
Perforated pipe or similar system is acceptable.
Tolerances: VY," in any 10-foot direction and 1/8” in any 3-foot direction.
Stone Selection: It is critical that different size stones are used so that the base shall be
uniformly mixed. The material shall be wetted during mixing operations if
necessary for proper blending.
