摘　　要：文章结合沈阳到山海关路面维修工程,研究了再生沥青混合料抗水损害问题。主要采用残留稳定度、冻融劈裂强度、冻融循环3种试验方法,从不同角度对再生沥青混合料的浸水条件下的物理力学性能进行分析,评价了混合料在抗水损害方面的路面使用性能。试验结果证明:再生沥青混合料抗水损害性能优良,能够满足使用要求。Moisture resistance of recycling old asphalt mixture is studied based on the pavement maintenance engineering of Shenyang-Shanhaiguan expressway . The physical mechanic properties are analyzed at a different angle by use of three test methods of the remained stability, thaw-freezing splitting strength and freezing-thawing. Thus the pavement performance of resistance to moisture damage is evaluated. The results show that recycled asphalt mixture is very good in resistance to moisture damage and can meet the requirements on use.
