PROBLEM TO BE SOLVED: To provide a manufacturing method for an asphaltic elastic pavement material which imparts high strength and excellent durability to a paved surface by improving adhesion properties between a binder and rubber, and the elastic pavement material capable of being obtained by the manufacturing method. SOLUTION: This manufacturing method is used for manufacturing the elastic pavement material which contains the binder containing asphalt and an ethylene-vinyl acetate copolymer, and rubber chips and/or rubber powder. The manufacturing method comprises a keeping step of keeping an obtained mixture at 100-190°C for 0.5-10 hours after the mixture is obtained by mixing at least the binder, and the rubber chips and/or the rubber powder together. In the elastic pavement material which is manufactured by the manufacturing method, the rubber chips and/or the rubber powder are/is swollen by the binder. COPYRIGHT: (C)2007,JPO&INPIT
