PR沥青改性技术在高速公路养护车辙治理中的应用

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。

The Application of PR Asphalt Modifying Technology in Maintaining the Expressway Rut

Proceeding from the production practice, the article gives the cause of expressway rut and points out the function of PR asphalt modifying technology in the testing repair of highway rut section. It also describes the choosing of modifying agent, the physical performance analysis, the material consumption and the mixing temperature of hybrid materials respectively. It is of great value because it uses a large number of test data.
