沥青路面反射裂缝分析与防治探讨

Reflection Crack of Asphalt Pavement and Its Prevention

反射裂缝是旧水泥混凝土路面上沥青罩面和半刚性路面的常见病害,对道路的危害极大。故对高等级公路沥青路面反射裂缝的产生机理进行分析,包括温度型反射裂缝和荷载型反射裂缝,然后在分析国内外道路现状的基础上,提出多种路面裂缝的预防及治理方法,对道路工程具有重要意义。

Reflection crack is a common disease of asphalt coat on old cement concrete pavement and semi-rigid pavement, which has great harm to road. The mechanism of production of reflection crack on asphalt pavement of expressway is analyzed, including temperature-reflection crack and load-reflection crack. Based on the analysis about the present situation at home and abroad, some methods for preventing and disposing pavement cracks are proposed, which have important significance to road engineering.
