Abstract:

In order to evaluate the performance of epoxy asphalt waterproofing adhesive layer, this paper adopts the shear test and the pull-off test to study the cohesive strength between epoxy asphalt and the basic plane of steel plate or concrete board, as well as the relationship between the strength and the temperature or curing time. Besides, this paper adopts the composite plate to simulate the experiment, then analyzes and compares the shear strength and pull-off strength of different waterproofing cohesive layer with different basic plane plate and asphalt mixture surfacing. The result shows that, epoxy asphalt binder as bridge structure waterproofing adhesive layer, its shear strength and pull-off strength is significantly better than any other type of materials, and its shear strength and pull-out strength to the steel plate are higher than cement plate. It indicates that epoxy asphalt is more suitable for steel bridge deck pavement. At high temperature condition, epoxy asphalt waterproofing adhesive layer has good bonding strength with the upper asphalt mixture structure layer. 8 tabs, 9 figs, 8 refs.
