PROBLEM TO BE SOLVED: To provide an elastic paving material having abrasion and wear resistance more than two times of the conventional asphalt paving. SOLUTION: An elastic paving material 10 is so constituted that it is a plate having 20-50 mm in thickness and that binder is mixed with elastic aggregate such as rubber chip or the like to compressively mold the mixture to harden. Ultrahigh molecular weight polyolefin thermoplastic resin coat is formed on the surface of the elastic aggregate in the surface. layer of the paving material. Specially, ultrahigh molecular weight polyethylene coat in the ultrahigh molecular weight polyolefin thermoplastic resin coat is suitable. The coat is formed by melting resin powder. Average particle size of the resin powder is 20-200μm. When average particle size of the powder is smaller than 20μm, the coat is not properly formed, and when average particle size is larger than 200μm, the powder is hard to melt.
