摘要
反射裂缝是旧水泥混凝土路面沥青罩面工程中的关键问题。对五种常用的反射裂缝防治措施进行了综述,并结合浙江省实际工程,讨论了各种方法的适用性以及防反射裂缝效果。为更加有效地解决反射裂缝问题,冲击压实、打裂压稳、碎石化等新技术也开始应用于白改黑工程中。
Controlling reflection cracking is a key technology for HMA overlays of PCC Pavement. In this paper, prevention methods for reflection cracking are systematic elaborated and applicability and effectivity were remarked based on asphalt overlays engineering in Zhejiang province. To prevent reflection cracking effectively, some new technology such as crack and seat, break and seat, rubbishing was applied.
