In order to extend the service life of asphalt roads, modification with polymeric materials is commonly used. In material modification, in addition to using chemical approach, physically accelerating polymerization reaction by irradiating the material with electron beams, which is used in the fields of automobiles, medical, pharmaceutical products, electrical and electronic materials. The purpose of this study was to understand the physicochemical properties of electron-beam-errddiated asphalt. Further more this study search for both the modified effect of asphalt and the recovery and regeneration of degraded asphalt. In the evaluation process, the asphalt was irradiated with an electron beam under various condition. Next, regarding the asphalt before and after irradiation, and evalc the changes in industrial properties, mixture properties, viscoelastic properties, composition and chemical stucture. These results shown that the physico chemical properties of asphalt were charge by irradiated with an electro beam, found modification effect on the asphalt. found modification effect on the asphalt.
