Abstract

The invention provides a steel bridge deck pavement structure which comprises a steel bridge deck slab; an epoxy zinc-rich primer anti-corrosion course is arranged on the steel bridge panel; an epoxy asphalt bonding waterproof course is arranged on the upper side of the epoxy zinc-rich primer anti-corrosion course; an epoxy asphalt concrete paving course is paved on the upper side of the epoxy asphalt bonding waterproof course; an epoxy asphalt bonding course is paved on the upper side of the epoxy asphalt concrete paving course; and a high-elasticity modified stone mastic asphalt course is paved on the epoxy asphalt bonding course. The steel bridge deck pavement structure is high in bonding strength, and not prone to damages of delaminating, slippage and the like; the waterproof performance is good, and the situation that water permeates and erodes a steel plate is not prone to occurring; and the corrosion resistance is high, and the service life of a bridge is prolonged. Therefore, epoxy asphalt is an excellent bonder, and is particularly suitable for an orthotropic steel bridge deck slab system.

Description

technical field [0001] The invention relates to the technical field of road and bridge structures, in particular to a steel bridge deck pavement structure. Background technique [0002] The stress and deformation of the steel bridge deck are much more complicated than that of the highway pavement, because of the deformation to a certain extent, there are higher requirements for the strength, deformation capacity, temperature characteristics and fatigue durability of the adhesive layer and the pavement layer. , steel bridge deck pavement technology is a worldwide technical problem that affects the durability of steel bridges. In the prior art, the asphalt concrete system is basically used for the pavement of the steel bridge deck. From the perspective of the selected materials and construction methods, the scheme design of "three materials and four structures" is basically formed: (1) Germany and Japan are The representative pouring asphalt concrete (Gussasphalt) scheme; the...
