摘要Based on surface energy theory, the surface energy parameters of SBS asphalt and cement concrete with different moisture contents are measured by the column wicking technique and the sessile drop method. Furthermore, the adhesion between cement concrete and SBS asphalt with different moisture contents is analyzed by calculating adhesion work. Then, the interlamination adhesive performance with different moisture contents is verified. The results indicate that (1) the adhesion work hit the maximum when moisture content is 0%, and the adhesion work decreases gradually as moisture content increases; (2) as moisture content decreases, the debond resistance performance of the waterproof adhesive layer improves, when the moisture content is 0.5%, the interlamination adhesive performance is insensitive to moisture content; (3) as moisture content decreases, the shear strength of waterproof adhesive layer on the bridge deck also improves, but the increment is not obvious after moisture contents is under 1.0%.
