摘　　要：针对沥青路面的低温开裂问题,选用一种环烷基为主、多种聚合物组成的沥青添加剂,对不同掺量下沥青结合料的针入度、软化点、延度等技术指标进行试验分析,确定最佳掺量,并进一步分析了该种添加剂对沥青混合料路用性能的影响。Aiming at the problem of low-temperature cracking of asphalt pavement,this paper selects an asphalt additive mainly composed of cycloalkyl and various polymers to test and analyze the technical indexes such as penetration,penetration index,softening point and ductility of asphalt binder under different dosage,determine the optimal dosage,and further analyze the influence of this additive on the road performance of asphalt mixture.

关 键 词：增延剂 沥青胶结料 最佳掺量 体积指标 路用性能
