摘　　要：针对内蒙古干线公路沥青混凝土路面耐久性不足的问题,提出采用高模量沥青混凝土的方法进行维修;研制了一种可用于沥青路面面层的高模量沥青混凝土增模剂,并在此基础上提出了内蒙古地区高模量沥青混凝土路用性能指标的合理取值范围。结合实际工程,对试验路段的渗水系数、构造深度及摩擦系数等指标进行了跟踪检测。结果表明:高模量沥青混凝土的整体性能及耐久性都有较大提高,适用于内蒙古中、西部地区特殊气候条件下的沥青路面。Aiming at the problem of insufficient durability of asphalt concrete pavement on the trunk roads of Inner Mongolia, it was proposed to treat with high modulus asphalt concrete. A modulus modifier fit for the surface course of asphalt pavement was developed, based on which a reasonable range of performance indices for high modulus asphalt concrete applied in Inner Mongolia was put forward. Combined with the practical use in projects, the tracking and detection of the seepage coefficient, texture depth and friction coefficient and other indicators were conducted on the test roads. The results show that the overall performance and durability of high modulus asphalt concrete are greatly improved, and it can be applied to asphalt pavement under special climatic conditions in the middle and western regions of Inner Mongolia.
