IAAF Track and Field Facilities Standards Manual required standard sports pole perimeter 400 meters, where the bend radius should be 36.5 meters, plastic runway project, the straight to avoid dazzling effect of low sun position along the north-south direction. The curve should be eight runway, each runway is 1.22 meters wide, has 10 straight runway. The inside of the runway safety area of ??not less than one meter, at best 1 meter outer security zone, starting area at least 3 meters, at least 17 meters sprint buffer segment. Shall not exceed the maximum inclination of the runway about 1: 1000, the plastic runway, downward gradient in the direction of running shall not exceed 1: 1000. Spray particles mixed plastic track its elastic layer (lower layer) and construction methods and ingredients mixed as traditional plastic runway. Surface use spray particles manner, campus plastic runway, to be integrated into a paste and an elastic layer color EPDM rubber particles with a polyurethane surface layer and then stir for plastic track surface layer with a special high-pressure spray evenly spraying machine, All were measured to be surface after the draw gauge line into a gel. Spray particles mixed plastic track due to surface wear layer is the use of EPDM rubber particles and the surface layer of polyurethane mixed slurry after mixing stir sprayed onto the elastic layer, playground plastic runway, the EPDM rubber particles are wrapped into the surface layer of polyurethane hybrid slurry, spray particles as compared with the traditional performance of solid particles scattered particles is much higher than traditional plastic track, and therefore less prone to the phenomenon of the use of threshing, cleaning plastic track surface is also easier and more convenient than traditional plastic track .
