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,沥青路面常常出现开裂、泛油、松散、拥包、推移、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,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。 As a road binder with asphalt, asphalt has been widely used in all countries of the world and become a long-term use of highway construction materials. 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 panping, loose bagging, bagging, pits and other common diseases. The appearance of these diseases seriously affects the driving speed, Safe, shorten the service life of asphalt pavement, increase the cost of road maintenance, reducing the road investment efficiency.
