Description

Technical Field

[0001] The utility model belongs to the technical field related to plastic runways, and particularly relates to a surface layer structure of a plastic sports ground. Background Art

[0002] The bases of the existing cast-in-place plastic sites are divided into asphalt bases and concrete bases. Since the asphalt base is a porous void type base, the cast-in-place two-component plastic material has good permeability to form a film and has good adhesion with the base to form an integral body. However, the cement base is flat, dense, and has tiny pores. It is very difficult for the cast-in-place two-component plastic material to penetrate into the interior of the base, and there are often quality problems such as delamination from the base when forming a film integrally, poor adhesion, and bulging.
