一、废旧轮胎在国外道路工程上的应用研究废旧轮胎在国外道路建设中的应用主要是将废旧轮胎橡胶粉应用于公路建设,这在国际上已有悠久的历史。20世纪60年代,Charles.McDonald发明了废旧轮胎橡胶粉改性沥青,先后被应用于道路的应力吸收层、应力吸收中间层,以及开级配、间断级配等沥青混合料中。经过20多年的技术探索和研发,到1988年前后,橡胶沥青在美国亚利桑那州、加利福尼亚州、德克萨
First, the application of discarded tires in road engineering abroad Abandoned tires in foreign road construction is mainly the application of waste tire rubber road construction, which has a long history in the world. In the 1960s, Charles. McDonald invented the waste tire rubber powder modified asphalt, which has been used in road stress absorption layer, stress absorption intermediate layer, as well as open grading, intermittent grading and other asphalt mixture. After more than 20 years of technological exploration and development, by the year 1988, rubber asphalt in the United States, Arizona, California, Texas
