The plastic track is laid whether in-situ construction or prefabricated into blocks, and the main structure of the plastic track consists of an elastic layer and a surface layer, wherein the surface layer has the functions of wear resistance and skid resistance and is divided into a particle type and a self-textured type; the elastic layer provides good elasticity and shock absorption. At present, the elastic layer is mostly formed by adopting polyurethane adhesives, mixing ethylene propylene diene monomer particles with a certain proportion, and casting or mould pressing. The existing plastic track has the problems that casting is influenced by material characteristics, process and weather, the phenomenon of material reduction caused by stole in the market and the like causes environmental damage caused by adding excessive organic solvent, excessive powder filling materials are added to cause the situation that the plastic track has no elasticity, the impact absorption performance and the vertical deformation performance generally do not reach the standard, and sports injury easily occurs, so that users such as athletes, students and the like in some projects are easy to be injured, and the plastic track has disordered market, low quality and short service life and seriously wastes social resources. The mould pressing type is formed by high-temperature mould pressing of ethylene propylene diene monomer, splicing is carried out on site, the mould pressing type is easy to age, harden and inelastic in the using process at present, the spliced part cracks and is separated from a base layer, the technical index required by movement cannot be reached, and the mould pressing production process needs high-temperature melting to be a high-energy consumption product, so that overlarge energy consumption and harmful influence on climate and environment are caused. In order to solve this problem, the industry has made improvements such as improving the properties of the adhesive, changing the proportions and materials of the elastic particles, etc., but the effects are not obvious and the intended purpose is not achieved. In addition, a water outlet is generally arranged near the plastic track; however, after rain, the water content of the base layer of the plastic track is too large, water bubbles or air bubbles exist on the ground, the water bubbles or air bubbles are not easy to discharge, the traditional plastic track is easy to bulge mainly depending on natural evaporation, and the quality and the service life of the whole plastic track are influenced to a certain degree.
