Plastic track belongs to a casting polyurethane elastomers, due to its high flexibility and high wear resistance silicon pu material cost is high, more and more used in the laying of a variety of sports venues, is internationally recognized as the current sports venues one pavement material. Plastic track and cinder, sand site compared to silicon pu water-based materials, with good elasticity, shock absorption, abrasion resistance and anti-aging, etc., do not pollute the environment, ease of cleaning and maintenance. Since the 19th Olympic Games, the Olympic Games athletics stadium previous main runway and the auxiliary area are made of plastic pavement, plastic runway has been internationally recognized as the best race track. Breathable plastic runway material type is a double spray polyurethane plastic runway runway system. Base layer is a polyurethane resin-bonded silicon pu black green rubber particles surface wear and surface layer of colored EPDM rubber particles after mixing with polyurethane spray form directly from the SMG machinery on the surface. Composite plastic runway base layer is a polyurethane resin-bonded black green rubber particles, the surface layer of colored EPDM rubber particles cast in polyurethane resin. Prefabricated plastic track is a prefabricated web runway. Natural rubber and rubber-based artificial mixed mineral fillers, stabilizers and colorants continuous rolling process in the factory, and 280-300 ℃ high temperature vulcanization curing one piece, mechanical embossing, consistent lines of the two-layer structure synthetic rubber. PU plastic track is mixed with black rubber granules made by mixing runway system. Material transported to the site by mixing, adding a catalyst stir silicon pu material, paving, room temperature vulcanizing, the surface layer is currently the only national standard plastic surface material, mainly used for professional racing venues. The main runway surface construction method plastic plastic runway construction plan and a construction program testing standards, clean space asphalt concrete construction is completed, The Nature Conservancy 28 days, clean asphalt surface dust with water cannons, and turn on the water to detect whether the site water, stagnant water chalk recorded and used plastic to fill the flat until no water so far. Second, the formwork to steel tape and theodolite accurate release formwork line, and formwork line between the runway center line, die and mold spacing of 2.44 meters (two channel width). Then 11MM mold section according to line accurate expenditure formwork mold frame, formwork primarily to ensure the plastic surface construction thickness (13MM) and flatness. Third, laying plastic surface layer 1, the pre-construction ground moisture determination: a sunny day with a thin transparent sticky tape around the wax on the ground. After two to four hours, if condensation inside the construction is not only in measuring ground water rate of 8% or less, before laying the plastic surface. 2, the mixed material mixing: a, stirring place to shop with plastic surface floor heating pad to ensure clean; b, the material is enabled, it must first clean the outer edge of the cover; c, Group A and Group B material according to a predetermined weight proportion into the mixing bucket, then add 20% of black rubber, and a certain amount of curing agent. Mixer should move around, and the material thoroughly mixed, but should avoid air into. 12d, the material should be poured directly into the mixing barrel central, not dumped along the bucket, so the bucket material can not be fully mixed.
