Steel bridge deck pavement layer

Abstract

The invention provides a steel bridge deck pavement layer. The steel bridge deck pavement layer comprises a prefabricated module layer and an anti-slip layer arranged on the surface of the prefabricated module layer. The steel bridge deck pavement layer is characterized in that the prefabricated module layer is fixedly adhered to the surface of an elastic transition layer; the elastic transition layer has self-leveling performance; and the elastic recovery rate of the elastic transition layer is not less than 95 percent. The steel bridge deck pavement layer provided by the invention is thin and light, so that the pavement dead load of a steel bridge deck can be greatly reduced; with the steel bridge deck pavement layer provided by the invention adopted, the problem that the steel bridge deck is not easy to flatten can be solved, the steel bridge deck pavement layer can be prevented from deforming and falling off in a using process, and meanwhile, the steel bridge deck pavement layer body can be prevented from locally fragmenting and sinking; the steel bridge deck pavement layer body disclosed by the invention is very excellent in durability and fracture resistance.

Description

Technical field [0001] The invention belongs to the technical field of steel bridge deck paving, and specifically relates to a steel bridge deck paving layer. Background technique [0002] In the prior art: Document CN210002255U provides a thin steel bridge deck paving structure suitable for laying on the girder bridge deck of a slow traffic system bridge, which includes a concrete base layer and a waterproof layer laid on the girder bridge deck in sequence And a paving layer, the paving layer includes a primer, a gravel layer and an antifouling layer, the primer is laid on the surface of the waterproof layer, the gravel layer is laid on the surface of the primer, The antifouling layer is laid on the surface of the gravel layer; document CN209584828U discloses a steel bridge deck paving layer, including: an adhesive layer arranged on the surface of the steel bridge deck; and an upper surface of the adhesive layer The composite material layer, the composite material layer is a po...

AI Technical Summary

Problems solved by technology

As mentioned above, the pavement layer of the steel bridge deck pavement structure has the following disadvantages: 1. There is a problem that the steel bridge deck is not easy to be paved during the pavement process; 2. The pavement body is easily deformed and easily deformed during use. The problem of shedding, especially after several years of use, the pavement body will also appear cracked or even sunken in some areas; 3. The durability and bending resistance of the pavement body are poor
