Study on the Interface Treatment of Concrete Deck Pavement

Today, serious deterioration has occurred on concrete deck pavement in China. One reason for the problem is the interface slippage between the concrete deck and the pavement. An efficient interface treatment can solve the problem. The interface treatment contains two aspects: the concrete deck treatment and the adhesion layer. Concrete deck treatment can change the physical form of the concrete deck and is more reliable in improving the shear performance of the concrete deck pavement. This paper summarizes and presents a comparison through physical form analysis and indoor tests of three kinds of concrete deck treatment: manual work treatment, milling treatment and sandblast treatment. The test results show that milling treatment can improve shear performance more than sandblast treatment. This paper suggests a more reliable way to improve the shear performance of concrete deck pavement.
