English Abstract

Application of Rubber Material (Asphalt Rubber) for Road Pavements Teruhiko MARUYAMA Department of Civil and Environmental Engineering Nagaoka University of Technology Nagaoka, Niigata, JAPAN Kazuo SUGA R & D Department Yokohama Rubber Co., LTD, Kanagawa, JAPAN Nippon Gomu Kyokaishi,(2005),78(10),388-392 General Review in Japanese Abstract Asphalt rubber (AR) is a blend, which includes 5-23 wt% of rubber component, of asphalt cement, reclaimed tire rubber, and certain additives. In this study, the samples have been prepared by so-called "wet process", which smoothly caused swelling and reaction of the rubber with hot asphalt cement. AR provides high quality road condition such as thermal cracking and rutting free surface, high skid resistance, low road noise, and so on. We have researched the factors which affect swelling and degradation of crumb rubber in the asphalt. Then, we can apply the result for the design of Japanese AR pavement, which is required premium grade quality. Keywords: Crumb rubber, Asphalt rubber, Asphalt pavement
