1, mixed plastic track construction program 1), environmental protection: non-toxic, pollution-free, in line with environmental requirements; 2), all-weather use: any season and temperature, can maintain a high standard of quality, the rain is more immediate use, increase use of time, space utilization improved; 3), flexibility: a moderate elasticity and rebound, can reduce the physical consumption, increase competition results; first need to be waterproof cement or asphalt foundation basis for back treatment. Base layer can be dealt with the underlying runway paving and maintenance 24 hours later, with the runway by GB-doped substrate particle size of 25% 3-4mm high elastic black rubber, stir into the venue, scraping rake Calibrating, laying thickness 9mm cured 24 hours maintenance. The audience into the runway surface material 2mm thick, scraping rake Calibrating the audience evenly planted 3-5mmEPDM skid particles, sweeping away any particles of cement after 24 hours of EPDM, roller or spray a layer of the runway after special finish .
