高等级沥青路面养护与维修技术

Maintenance and Repair Technology of High Grade Asphalt Pavement

目前,我国大多数高等级公路均为沥青路面。在高等级公路沥青路面投入使用过程中,常常会出现多种不同的病害问题,严重影响高等级公路的安全性,减少高等级公路的使用寿命。基于此,本文首先论述了高等级公路沥青路面常出现的病害问题,然后详细阐述了高等级公路改扩建工程的维修与高等级公路沥青路面的养护,具有重要意义。

At present, most of the high-grade highways in China are asphalt pavement. In the process of high-grade highway asphalt pavement put into use, there are often many different diseases, which seriously affect the safety of high-grade highway and reduce the service life of high-grade highway. Based on this, this paper first discusses the common problems of high-grade highway asphalt pavement, and then elaborates the maintenance of high-grade highway reconstruction and expansion project and the maintenance of high-grade highway asphalt pavement, which is of great significance.
