1、I摘 要沥青路面是在柔性基层、半刚性基层上，铺筑一定厚度的沥青混合料作面层的路面结构。沥青路面与砂石路面相比，其强度和稳定性都大大提高;与水泥混凝土路面相比，路面平整无接缝，行车振动小，噪声低，建设工期短，养护简便，具有良好的力学韧性、延展性、耐久性，而被广泛采用，是我国重要的路面结构形式。但是随着我国经济快速、办调发展，交通量不断增长，加之沥青路面受外界条件影响及因设计、施工和养护等诸多种原因，很多沥青路面公路出现一定的早期破坏，如裂缝、麻面、松散、坑槽、车辙、拥抱、波浪和沉陷等破损问题比较突出，直接影响了公路的顺利运行，并且这些病害的出现加大了养护管理资金的投入，严重影响了行车的舒适与安全
