摘要： 为了对稀浆封层层间黏结性能进行评价,自行设计了以改进的剪切仪为基础的试验方法,能较好地模拟路面真实受力情况.试验结果说明,随着温度的升高,稀浆封层与沥青碎石下面层之间黏结强度在减小;不同的路面层间处理措施对黏结强度均有明显的影响;采用较大公称粒径的沥青混合料,或者对路面做凿毛处理均可以有效提高层间黏结强度.

Abstract: To evaluate the interlayer bonding strength between slurry seal and pavement, an experimental setup was designed on the basis of improved shear tester, with the aim to model well the actual condition of loaded pavements. Experimental result showed that the interlayer bonding strength between the slurry-sealed coat and asphalt-macadam bottom layer decreases with increasing temperature. Taking some different measures to improve interlayer conditions of pavement can affect obviously the bonding strength, such as using asphalt-macadam mixture with big nominal grain size or making the pavement surface coarse by chisel.
