国省道干线公路沥青路面病害识别与养护决策研究

Research on Identification and Maintenance Decision of Asphalt Pavement Defects on National and Provincial Trunk Highways

随着我国经济的快速发展和城乡一体化进程的加速,国省道干线公路作为连接城市与城市、城市与乡村的重要纽带,直接关系区域经济的发展和人民生活的便捷。沥青路面作为国省道干线公路的主要铺装材料,因其良好的平整性,被广泛应用于公路建设中。然而,沥青路面在使用过程中会因环境因素和交通荷载的影响,出现裂缝、车辙、坑槽等各种病害,从而降低道路的使用性能,增加养护成本,甚至影响行车安全。本文主要论述国省道干线公路沥青路面典型病害及其养护技术,为公路建设者提供有价值的参考。

With the rapid development of China's economy and the acceleration of urban-rural integration,national and provincial trunk highways,as important links connecting cities and rural areas,are directly related to the development of regional economy and the convenience of people's lives.Asphalt pavement,as the main paving material for national and provincial trunk highways,is widely used in highway construction due to its good smoothness.However,during the use of asphalt pavement,various diseases such as cracks,ruts,and potholes may occur due to environmental factors and traffic loads,thereby reducing the performance of the road,increasing maintenance costs,and even affecting driving safety.This article mainly discusses the typical diseases and maintenance techniques of asphalt pavement on national and provincial trunk highways,providing valuable references for highway builders.
