Abstract:
In order to evaluate the impact of interlayer interface on the structural performance of bridge deck pavement, the high temperature performance and the change of shearing strength during the flexural fatigue are studied on the base of wheel tracking test and shearing test after flexural fatigue of combined specimens for different interfaces. Through analyzing the test results, the rutting depth of one hour later，dynamic stability and shearing strength of different flexural fatigue times for different interface combined specimens are obtained. The results show that textures of interface between layers have a significant impact on the high temperature performance of paving layer and the attenuation of shearing strength for interlayer. When the textures are more rich, the interface based on microtexture mainly is conducive to the spread of load stress, and it can reduces the stress of paving pavement, so it improves antideformation capacity indirectly. The shearing strength, which is the major source of friction between two layers, will have a lower decay rate than those reliance on major interlayer bonding force.8 tabs, 1 fig, 8 refs.
