A steel bridge deck pavement structure transition layer

Abstract

The invention provides a transition layer of a steel bridge deck pavement structure, which is prepared by blending a reactive resin and a filler with a particle size of less than 5 mm. The elastic recovery rate of the transition layer is not less than 98%. The compression ratio is not more than 4%. The transition layer provided by the present invention not only has excellent elastic recovery rate and self-leveling performance, but also can make the transition layer thin and light; using the transition layer provided by the present invention in the steel bridge deck pavement structure can not only solve the problem of The steel bridge deck is not easy to be paved, and it can prevent the steel bridge deck pavement structure from deforming and falling off during use, and can also prevent local area cracking inside the pavement structure.

Description

technical field [0001] The invention belongs to the technical field of steel bridge deck paving, in particular to a transition layer of a steel bridge deck pavement structure. Background technique [0002] In the prior art: Document CN2017105784945 provides an assembled steel bridge deck for medium and small span bridges and an assembling method thereof. The structure of the steel bridge deck is that a plurality of square steel pipes are vertically inserted and connected side by side through round steel pipes to form an integral plane. , and then fixed with bolts; the square steel pipe is filled with concrete filler, and on the overall plane, a concrete leveling layer and an asphalt pavement layer are arranged in turn; the document CN2005100969105 provides a bridge deck paving for a large-span steel bridge The installation structure consists of steel bridge deck, waterproof adhesive layer, transition layer, waterproof adhesive layer and asphalt pavement layer. The transition...
