Abstract

The invention provides a steel bridge deck paving structure, comprising an anti-corrosion layer, an elastic transition layer, a bonding layer, a polymer prefabricated profile layer and an anti-slip layer sequentially laid on the steel bridge deck; the elastic transition layer adopts a reactive resin It is prepared by blending with fillers with a particle size of less than 5mm, and the reactive resin is one or more combinations or modified products of polyurethane, modified epoxy resin, methacrylic resin, liquid silicone rubber, and liquid polysulfide rubber. The polymer prefabricated profile layer adopts a spliced ​​structure, and the polymer prefabricated profile layer is a prefabricated profile layer made of thermoplastic resin or thermosetting resin or its modification; the anti-slip layer is made by blending reactive resin and aggregate. The steel bridge deck pavement structure of the invention not only has excellent low temperature cracking resistance and fatigue resistance, but also has excellent wear resistance and flexural resistance, and also has excellent high stability and anti-load deformation ability. The long life of the ultra-thin steel bridge deck pavement structure.
