摘要
着重介绍了路面坑槽产生的原因,冷补沥青混合料的特点及今后的发展趋势。沥青混凝土路面在高等级公路中所占的比例越来越大,路面坑槽病害是一种非常严重的病害,传统的坑槽修补方法多是热拌沥青混合料的修补方法,这种方法对温度的要求很高,技术复杂。冷补沥青混合料不需加热,适应能力强,是一种方便可行的坑槽修补材料。
The asphalt-concrete pavement takes up more and more proportion in the construction of high-grade expressway. Pavement pothole disease is a kind of very serious disease. The traditional pothole repair method mostly adopts heat asphalt mixture, which needs higher temperature and complicated techniques. Cold repair asphalt mixture doesn＇t need heating, and has strong adaptability to the surroundings, which is a convenient and feasible pothole distresses material.
