Abstract
The emulsion wax coating agent is a kind of new material about the isolation layer of cement concrete pavement (CCP). It could formed isolation layer between surface layer and base layer (also called emulsion wax isolation seal coat) when it sprayed on the base course surface of CCP. The CCP’s emulsion wax isolation layer was provided with functions of isolation, friction reduction, waterproofing and so on, which could reduced the degree of bonding between the surface layer and the base layer, to weak the formation of weak transition layer (abbreviated “transition layer”) in construction process of the concrete pavement’s surface. The research of CCP’s emulsion wax isolation layer is still remained in the “qualitative” level at present. With electronic microscope, mercury porosimeter and so on. This paper developed the research of set the structure of EWCA’s isolation layer pavement (macrostructure, mesoscopic and micro structure) and the infiltration of wax isolation agent. And further through the surface of base course texture depth test, infiltration test, anti-erosion test, interlayer adhesion and friction coefficient test and other methods, bond strength between layers and friction coefficient test which analysis in-depth the research of wax isolation layer’s mechanism of action in aspect of isolation, reduce friction, watertightness, improved the performance of the transition layer and so on, which established the coulomb model of interlayer adhesion and friction, etc. And indicated the mechanism of action of CCP’s emulsion wax isolation layer.
