Abstract

Authors explored the mechanism of using emulsion wax curing agent as separation layer to break the bond between cement concrete pavement slabs and lean cement bases and discussed its separation effectiveness via a series of tests, such as swinging friction coefficient tests, shear tests between layers, torsion tests and pulling tests. The material requirements for emulsion wax curing agent used as separation layer were set under the relevant standard, literature at home and abroad and the results of the tests conducted in the paper. The results indicate that emulsion wax curing agents sprayed between cement concrete pavement slabs and lean cement bases are able to effectively reduce the bond between layers and the shear between layers under given circumstances. Using emulsion wax curing agent as separation layer of pavements is cost-efficient and feasible method.
