沥青路面典型病害的机理及其防治措施研究

Research on the Mechanism and Prevention Measures of Typical Diseases of Asphalt Pavement

随着沥青材料的发展,沥青路面逐步广泛应用于公共道路建设中。沥青路面作为路面的主要结构层之一,受施工质量和材料自身老化的影响,随服役时间不断延长,在自然条件和车辆荷载的耦合作用下,易出现裂缝、坑槽、车辙等病害,对行车的安全性和舒适性造成严重影响,同时降低了道路使用寿命。首先总结了沥青路面的几种典型病害,分析了其形成机理,在此基础上,提出了病害的预防治理思路与具体措施,以期为沥青路面病害的防治提供参考。

With the development of asphalt materials, asphalt pavement is gradually widely used in public road construction. As one of the main structural layers of the pavement, the asphalt pavement is affected by the construction quality and the aging of the material itself.With the continuous extension of service time, under the coupling action of natural conditions and vehicle loads, cracks, potholes, ruts and other diseases are prone to occur. Driving safety and comfort have a serious impact, while reducing road life. This paper summarizes several typical diseases of asphalt pavement and analyzes its formation mechanism. Based on this, the prevention and treatment measures of the diseases are proposed, in order to provide reference for the prevention and treatment of asphalt pavement diseases.
