通过对高速公路车辙产生的原因进行分析,从生产实践出发,说明PR沥青改性技术对车辙路段进行试验性修复的作用。本文从改性剂选择、物理性能分析、材料用量,以及混合料拌合温度的确定等多个方面分别进行论述,采用大量试验数据加以说明和分析,具有一定的推广价值。
Based on the analysis of the causes of rutting on expressway, the paper describes the effect of PR modified asphalt technology on experimental repair of rutting sections from the production practice. This paper discusses the selection of modifier, physical property analysis, the amount of material, and the determination of the mixing temperature of the mixture, and so on. It uses a lot of experimental data to illustrate and analyze, which has a certain promotion value.
