沥青路面抗车辙性能提高策略分析

Analysis on Strategies for Improving Rutting Resistance of Asphalt Pavement

根据当前我国沥青路面运营情况来看,80%以上的路面维修养护都是由车辙变形导致的,危害性较大。此外,与其他路面病害相比,车辙维修难度最大,因为车辙现象不仅发生在沥青路面表层,还常常涉及中下面层。论文主要探讨沥青路面车辙形成机理与影响因素,从优化路面结构设计、合理选择施工材料、强化施工质量管理、完善运营管理机制等方面提出提高沥青路面抗车辙性能的策略。

According to the current operation of asphalt pavement in China,more than 80%of pavement maintenance is caused by rutting deformation,which is harmful.In addition,compared with other pavement diseases,rutting is the most difficult to repair,because rutting phenomenon not only occurs on the surface of asphalt pavement,but often involves the middle and lower layers.This paper mainly discusses the forming mechanism and influencing factors of rutting on asphalt pavement,and puts forward strategies to improve rutting resistance of asphalt pavement from the aspects of optimizing pavement structure design,rationally selecting construction materials,strengthening construction quality management and perfecting operation management mechanism.
