Abstract：Inorder to improve the performance of waterproof adhesive layer of permeable pavement，a modified emulsifiedasphalt was prepared bySBS modified asphalt，concentrated hydrochloricacid，asphalt emulsifierand other materials，and then the waterproof adhesive layer was sprayed on the surface of permeable concrete substrate， and the performance of the waterprof adhesive layer was studied.The results show that the tensile strength of the waterproof adhesive layeris O.36MPaandthe shear strength is O.88 MPa.Atthe same time，the tensile strength and shear strength decreased by 13.89% and 9.09% respectively in the water mist environment. In the dusty environment，the tensile strength and shear strength decreased by 22.22% and 13.64% ，respectively. Moreover，the waterproof adhesive layer has good construction eficiency and economy in construction application.In summary，the modified emulsified asphalt waterproof bonding layer has good bonding performance and can promote the development of waterproof bonding layer materials for permeable pavement.
