Abstract

In order to improve the durability of steel bridge deck pavement, this paper evaluated the mechanical response law of epoxy asphalt pavement with thicker steel bridge deck based on the static load test of solid steel bridge deck pavement and analyzed the transverse strain distribution, critical load, overload effect, axial and transverse strain difference, and the strain condition of epoxy asphalt pavement structure. It identified the mechanical behavior law of epoxy asphalt pavement. The results show that the bridge deck structure is basically in an elastic state under axle load; the surface strain of the bridge deck increases obviously with the increase in axle load, and the effect of wheel load on the steel bridge deck exists within the radius of 1 m. The upper edge of the axial stiffener web of the bridge deck is in the most unfavorable tension state, and fatigue cracking is easy to occur under the repeated action of wheel load. The transverse strain on the lower surface of the steel bridge deck is obviously higher than the axial strain. Epoxy asphalt pavement is mainly characterized by elastic characteristics.
