低等级公路沥青路面加铺沥青防裂研究

Asphalt Overlay Crack Prevention of Low-grade Highway Asphalt Pavement

反射裂缝的防治是低等级公路沥青路面加铺沥青层时需要克服的重要问题,以铜仁市某路面改善提升工程为例,对低等级公路沥青路面沥青加铺层反射裂缝形成机理进行了简要分析,提出了一系列防止或减缓反射裂缝形成的措施。

The prevention of reflection cracks is an important problem to be overcome when asphalt layer is added to low-grade highway asphalt pavement.Taking a pavement improvement project in Tongren as an example,this paper briefly analyzes the formation mechanism of reflection cracks in asphalt overlay of low-grade highway asphalt pavement,and puts forward a series of measures to prevent or slow down the formation of reflection cracks.
