当前随着国家经济的不断发展,公路工程也取得了很大了成绩。我国目前正在施工建设或者已竣工营运的公路项目有很大部分采用的是半刚性基层沥青路面。随着公路交通运营量的不断增大,道路路面也要面对各种考验,道路病害现象不断发生。路面裂缝问题是工程领域中最常见的一种病害,当路面出现裂缝,路面积水会从路面裂缝处向路面基层渗入,然后使基层或者路基出现软化现象,使路面的承载能力减小,路面的破坏则越来越严重,严重影响车辆行驶的安全与舒适性。
At present, with the continuous development of the national economy, highway projects have also achieved great success. A large part of highway projects under construction or completed operation in our country are semi-rigid base asphalt pavement. With the continuous increase of traffic volume of road traffic, the road pavement has to face various tests as well, and the road disease phenomenon continues to occur. The problem of crack in pavement is the most common one in engineering field. When there are cracks in pavement, water from pavement infiltrates into the pavement base from cracks in the pavement, softens the grassroots or roadbed, reduces the carrying capacity of the pavement, The damage is more and more serious, seriously affecting the safety and comfort of vehicles driving.
