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,选择PR沥青改性技术对车辙路段进行试验性修复。本文从改性剂选择、物理性能分析、材料用量,以及混合料拌和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。
Based on the analysis of the causes of expressway rutting, from the production practice, we choose PR asphalt modification technology for experimental repair of rutting sections. In this paper, the selection of modifiers, physical properties, the amount of materials, as well as the mixing temperature and other aspects of the determination were discussed, using a large number of experimental data to illustrate and analyze.
