A. “Type B Tire Derived Aggregate (ASTM D6270)”

Type B

Type B TDA shall have a minimum of 90% (by weight) with a maximum dimension, measured in any direction, of 300-mm(12”) and 100% with a maximum dimension, measured in any direction, of 450-mm(18”). At least one side wall shall be removed from the tread of each tire. The side wall will be considered removed if the bead wire has been completely severed from the side wall. A minimum of 75% (by weight) shall pass the 200-mm(8”) square mesh sieve, a maximum of 50% (by weight) shall pass the 75-mm(3”) square mesh sieve, a maximum of 25% (by weight) shall pass the 38-mm(1.5”) square mesh sieve, and a maximum of 1 % (by weight) shall pass the 4.75-mm(.2”) sieve.

B. “Type A Tire Derived Aggregate (ASTM D6270)”

Type A

Type A TDA shall have a maximum dimension, measured in any direction, of 200-mm(8”). In addition, Type A TDA shall have 100% passing the 100-mm(4”) square mesh sieve, a minimum of 95% passing (by weight) the 75-mm(3”) square mesh sieve, a maximum of 50% passing (by weight) the 38-mm(1.5”) square mesh sieve, and a maximum of 5% passing (by weight) the 4.75-mm(.2”) sieve.

C. “Superstone”

Type C

Tire shreds shall not exceed 7” in length. 100% of material must pass 4-inch screen. Metal must be 95% embedded in rubber. Wire strands may not protrude more than ½” from side of shred.
