摘要
分析了沥青加铺层反射裂缝产生的原因,并从锯切横缝、增加加铺层厚度、裂缝缓解层、设置夹层、提高面层性能几方面,介绍了防治反射裂缝的措施,以有效地改造旧水泥混凝土路面,改善沥青加铺层使用品质。
The article analyzes the causes of reflection crack in asphalt overlay, and introduces measures to prevent such crack from saw cutting transverse joint, increasing the length of overlay, cracking relief layer, setting interlayer, and increasing the performance of surface course, in order to effectively reconstruct old cement concrete pavement and perfect the quality of asphalt overlay.
