沥青作为一种路用结合料,在世界各国得到了广泛的应用,从乡村道路到城市道路,从三级路到高速公路,从路面底基层到路面面层,均普遍采用。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、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。 As a road binder, asphalt has been widely used in all countries of the world, from rural roads to urban roads, from tertiary roads to expressways, and from road base to grass-pavement. Become a long-term use of highway construction of a material. Due to the difference of asphalt material itself and the influence of design and construction level, common defects such as cracking, oil pan and pit are frequently appeared in asphalt pavement. The occurrence of these diseases has seriously affected the driving speed, driving safety and increased automobile wear , Shorten the service life of asphalt pavement, affecting the road investment efficiency.
