Abstract:
In order to solve the diseases including spalling, loose and upheaval caused by lacking of shear strength and bond strength of bridge pavement layer, this paper studied the influence of optimum content of different waterproof films, different shear rates and different temperatures on the interlayer shear strength by using MTS810, shear apparatus and pullout apparatus. It also analyzed the bond strength of different water proof films to accurately select water proof film. The results indicated that: SBS modified asphalt and modified asphalt emulsion have a good shear performance; the variety of shear rate has a significant effect on the shear strength of SBS modified asphalt; the high temperature resistance of SBS modified asphalt is the best; the bond strength of modified asphalt emulsion and SBS modified asphalt is fairly high, and they have good extension properties; the relationship between interlayer shear strength and bond strength is a quadratic curve. 4 tabs, 5 figs, 10 refs.
