随着交通量的增大,公路等级的逐步提高,高等级沥青混凝土路面得到了广泛的应用。但是,随着公路的陆续建成并投入运营后,沥青路面早期损坏较为普遍,如路面沉陷、桥头跳车、车辙、泛油、坑洞等,造成这些病害的一个重要原因就是由于水的浸蚀;而另外一些原因,如温度变化导致路面产生的裂缝,为雨水浸入路面及路基创造了条件,又加剧了路面的破坏。可以说,水的浸蚀是当前影响公路路况,造成沥青路面损坏的重要原因。
With the increase of traffic volume and the gradual increase of highway grade, high grade asphalt concrete pavement has been widely used. However, as the roads are built and put into operation one after another, the early damage of asphalt pavement is more common, such as road surface subsidence, bridge jumping, rutting, oil flooding and potholes, etc. One of the important causes of these diseases is water erosion ; While other reasons, such as the cracks caused by temperature changes, have created conditions for rainwater to enter the pavement and subgrade, further aggravating the destruction of the pavement. It can be said that the erosion of water is the current impact on road conditions, resulting in asphalt pavement damage is an important reason.
