Description

Technical Field

[0001] The utility model relates to the technical field of plastic runways, in particular to an environment-friendly prefabricated plastic runway. Background Technique

[0002] A plastic runway, also known as an all-weather track and field runway, is a sports ground runway made of plastic or rubber. The plastic runway is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. At present, there are various types of plastic runways, including environment-friendly prefabricated plastic runways.

[0003] The existing environment-friendly prefabricated plastic runway still has the following problems in use: usually, two layers of asphalt structures are laid at the bottom of the runway main body, including a layer of coarse asphalt at the bottom and fine asphalt located above the coarse asphalt. However, since the coarse asphalt is directly laid on the ground and the plastic runway is usually subjected to irregular high loads, it is extremely easy to cause irregular settlement of the asphalt installation ground, and then cause fracture and damage of the plastic surface of the plastic runway.
