沥青路面水损害分析与防治

Analysis and Prevention of Water Damage on Asphalt Pavement

随着城市交通的大力发展,公路建设中的各种病害防治工作日益引起工程技术人员的重视,其中路面的湿害是一个重要的问题。在我国,路面表层大多由沥青混凝土、半刚性材料作为基层,其中水损害是沥青路面的早期损害之一。本文在分析沥青路面水损害成因的基础上,从外部和内部两个方面研究水损害的类型以及形成机理,并提出了防治措施。

With the development of urban transportation,the prevention and control of various diseases in highway construction has increasingly attracted the attention of engineering technicians,among which the wet damage of the pavements is an important problem.In China,asphalt concrete and semi-rigid materials are mostly used as the base course of pavement surface,and water damage is one of the early damages of asphalt pavement.Based on the analysis of the causes of water damage of asphalt pavement,this paper studies the types and formation mechanism of water damage from the external and internal aspects,and puts forward the preventive measures.
