[0002] The functional area of ββthe sports field is generally a football field in the middle of the field, and a field field and a circular competition track are set around the football field. The surface layer of the circular competition track of the previous sports field is generally paved with carbon slag as the main material. The elasticity of this type of surface layer is not easy to maintain. It is loose at the beginning and is not conducive to running. It is easy to harden after being exposed to the sun and rain, which is also not conducive to running. With the use of polyurethane rubber (PU) track, it has been widely used for its bright colors and small dust. The current sports field generally adopts polyurethane rubber (PU) track surface. However, the polyurethane rubber runway has the following di...
