Full plastic plastic track Features: The main material is a two-component polyurethane, the base layer of natural rubber and artificial rubber basketball courts plastic runway, mixing mineral fillers, stabilizers and colorants at 280-300 ℃ high temperature vulcanized sclerosis integrally molding. Combine sports science and materials science, and reflect the athletes can fully meet the professional requirements of participants runway. Polyurethane plastic runway graded gravel layer (1) maximum particle size of sand and gravel mixture should not exceed 2/3 of the thickness of the sand layer. Block shop design thickness shall be multiplied by the thickness of 1.2-1.25 compaction factor, such as 20CM thick sandstone layer plastic runway, thickness should be thick 24-25CM; (2) to be uniform paving gravel tennis courts plastic runway, no the thickness of the particle separation phenomenon, paving gravel 30-50 meters in length sports plastic track, start splashing water, the amount of humidity and temperature and moisture content of materials related to gravel, sand and gravel to make all wet as well, until the surface is slightly back splash dry, moist, rolling to not loose mix so far. If there are sand pit and plum phenomenon, should excess sand dug, respectively penetrate the right amount of sand or sand for processing. (3) quality standard sand layers: A, compaction density 2.30KG / liter or more; B, thickness tolerance + 10%; C, aspect off the elevation tolerance + 2CM; D, a width of not less than the design width; E Appearance: smooth surface density, no sand hole, plum and other phenomena; F, heavy rolling track depth of less than 5MM; basketball courts plastic runway, Camry sports (certified), Heyuan plastic runway by the Dongguan City Camry sports facilities Limited.
