Plastic surface layer of elastic bead track for athletic running

The invention relates to a surface layer material of an athletic field, and aims to provide a plastic surface layer of an elastic bead track for athletic running. The plastic surface layer has the characteristics of good friction performance, excellent impact and absorption property, firm structure, excellent durability, water permeability and air permeability. According to the technical scheme, the plastic surface layer of the elastic bead track for athletic running comprises a plurality of near-spherical macromolecular elastic body beads, and is characterized in that the near-spherical macromolecular elastic body beads are piled up to form the plastic surface layer with a certain thickness, the adjacent elastic body beads are connected one another integrally through adhesives of portionswhich are in contact with one another, or the portions which are in contact with one another are fused and adhered integrally; and the other portions form irregular hollowed-out gaps. 本发明涉及种运动场地表层材料。目的是提供种弹性珠粒田径跑道塑胶面层，该塑胶面层应
