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.
