新型改性剂在道路交叉路口路面改造中的应用

摘要

Asphalt pavement rutting is the main disease of urban roads, which can reduce the pavement smooth-ness and shorten the service life of city roads. This paper, taking the pavement reconstruction project of a road intersection as an example, analyzed the road performance and economic benefits of three kinds of modified as-phalt mixture. It maintains that the use of suitable modifiers can improve the anti-rutting performance of asphalt pavement, which plays a key role in solving the pavement rutting problem.%城市道路主要病害是沥青路面的车辙，也是导致路面平整度降低的主要原因，降低城市道路的使用寿命。以某路段交叉口沥青路面改造工程为例，对3种改性剂沥青混合料的路用性能及经济效益进行分析研究，选择合适的改性剂，提高沥青路面抗车辙性能，对解决路面车辙问题可以起到关键作用。
