The Interface Bonding Performance Experiment Analysis of Slag Base Cement Concrete Pavement Repair Material

Abstract:

Due to the effect of various additional stress,cement concrete pavement repair material and the original road interface been damaged,which cause pavement breakdown. In order to solve this problem,this paper analyzing the reason of new and old concrete interface weakness and the require of interface bonding performance,the flexural bonding experiment method is used to test performance,and to verify slag base as a new type of repair material,which matched with cement paste contains expansion agent as an interface boning agent.Results shows that this new repair material can satisfy the interface bonding performance requirements very well.
