公路路面扩宽施工中的老路面处理

Old Pavement Treatment in Highway Pavement Widening Construction

我国公路工程长期处于新旧更替的过程中,在长期的使用过程中,老公路性能逐步降低,其路面宽度、承载力等无法满足当前的通行量要求。因此,人们往往需要在原有公路路面的基础上进行扩宽处理,其中,老路面的处理是路面扩宽工程的重点与难点。

China's highway engineering has been in the process of new and old replacement for a long time.The performance of old highways has been gradually reduced during long-term use,and its road width and bearing capacity cannot meet the current traffic demand requirements.Therefore,people often need to carry out widening treatment on the basis of the original road surface.Among them,the treatment of the old road surface is the key and difficult point of the road widening project.
