Abstract

The invention provides a steel bridge deck pavement structure. The steel bridge deck pavement structure comprises an anti-corrosion layer, an elastic transition layer, a bonding layer, a macromolecule prefabricated profile layer and an anti-sliding layer which are sequentially laid on a steel bridge deck slab. The elastic transition layer is prepared by blending reaction type resin and filler with the particle size smaller than 5 mm, and the reaction type resin is one or a combination of more of polyurethane, modified epoxy resin, methacrylic resin, liquid silicone rubber and liquid polysulfide rubber or a modifier of the polyurethane, the modified epoxy resin, the methacrylic resin, the liquid silicone rubber and the liquid polysulfide rubber; the macromolecular prefabricated section bar layer adopts a spliced structure, and is a section bar layer prefabricated by adopting thermoplastic resin or thermosetting resin or modified substances thereof; and the anti-skid layer is prepared by blending reactive resin and aggregate. The steel bridge deck pavement structure disclosed by the invention not only has very excellent low-temperature cracking resistance and fatigue resistance, but also has excellent wear resistance and fracture resistance, and also has excellent high stability and load deformation resistance, so that the long service life of the ultra-thin steel bridge deck pavement structure is really realized.
