PR沥青混合料在重交通路面施工中的应用

Application of PR asphalt mixture in heavy traffic pavement construction

结合施工经验,介绍了PR沥青混合料在高速公路中的原材料控制要点,分析了PR抗车辙剂提高路面抗车辙性能的作业机理,并从混合料设计、拌和及碾压等方面探讨了各工序要点,以期借鉴。

Combining with construction experience,the paper introduces raw material control points of PR asphalt mixture in highway,analyzes working mechanism of PR anti-rutting agent in improving pavement anti-rutting performance,and explores mixture design,mixing and rolling construction technology points,with a view to provide some guidance.
