摘　　要：为解决长陡坡路段车辙病害严重的问题,结合工程实例,分别从机理分析、沥青制备、室内沥青混合料车辙试验以及现场试验分析等方面对高模量沥青进行研究。研究结果表明:高模量沥青混合料比传统的SBS改性沥青混合料抗车辙性能提高近30%,改善作用明显,可为相关工程应用提供参考。To improve the rutting phenomenon in the long steep road, the article provides high modulus asphalt method. Based on an engineering project, the paper made researches on mechanism analysis, asphalt preparation, indoor asphalt mixture rutting test and field test and so on. The results showed that comparing with traditional SBS asphalt mixture, the anti - rutting of the high modulus asphalt mixture increase by 30% and the improving effects is obvious, providing the reference for the related engineering application.
