目前,沥青作为路用结合料,在世界各国得到了广泛的应用,成为公路建设长久使用不衰的一种材料。但由于沥青材质本身的差异,以及受设计和施工水平的影响,沥青路面常常出现裂缝、水破坏、松散、泛油、推移等早期病害,这些病害的出现严重影响了行车速度、行车安全,缩短了沥青路面使用寿命,增加了道路的维修成本,降低了道路投资效益。本文就以上几种病害及其成因进行分析阐述。
At present, as a road binder, asphalt has been widely used in all countries in the world and has become a kind of material that has been used for a long time in highway construction. However, due to the difference of asphalt material itself and the influence of design and construction level, the early deterioration of asphalt pavement often occurs such as cracks, water damage, looseness, oil panping and so on. The occurrence of these diseases seriously affects the driving speed, driving safety and shortening The service life of asphalt pavement increases the maintenance cost of the road and reduces the investment efficiency of the road. This article analyzes the above diseases and their causes.
