Aiming at the disadvantages of the current evaluation method of the damage of interlayer bonding effect of cement concrete composite bridge pavement,the functional relations between interlayer bond strength and shear strength and adhesion of composite structure under specific bridge pavement structure and material conditions are established by laboratory tests,and the temperature correction coefficient is obtained in this paper.The interlayer bond strength and shear strength of the composite structure are calculated according to the measured adhesion of the waterproof bond layer on the project site,and then converted to the standard strength value at 20 ℃.The quality evaluation of the actual engineering interlayer combination effect is carried out with reference to the relevant standards.The results show that there is a strong linear positive correlation between the adhesion of waterproof bonding layer to cement concrete and the interlayer bonding strength and shear strength of composite structure,and the error between the predicted value and the measured value is basically within 10％.The interlayer bonding effect can be evaluated directly with the help of the specification after the predicted strength value is converted to the standard value.
