沥青作为一种路用结合料,在世界各国得到了广泛的应用。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,沥青路面常常出现开裂、泛油、松散、坑槽等常见病害,这些病害的出现严重影响了行车速度、行车安全,加大了汽车磨损,缩短了沥青路面使用寿命,影响了道路投资效益。针对这些问题作了比较深入的探讨,并提出了一些在施工中需要注意的技术要点。 As a road binder, asphalt has been widely used in all countries in the world. However, due to the difference of asphalt material itself and the influence of design and construction level, asphalt pavement often has common diseases such as cracking, oil panpipe, looseness and pit. The occurrence of these diseases has seriously affected the driving speed, driving safety and increased the car Wear and shorten the service life of asphalt pavement, affecting the road investment efficiency. In order to solve these problems, we made a more in-depth discussion and put forward some technical points that need attention in construction.
