Problems solved by technology

Its main disadvantages are: poor high temperature stability, easy to form ruts
The main disadvantages are: the preparation process of epoxy asphalt concrete is relatively complicated, the time and temperature requirements are very strict during construction, and the construction is difficult. Most of the related technologies are patented products abroad, and the cost of materials is also high.
[0012] Solvent-based adhesive has the advantages of easy spraying and normal temperature construction, but its bonding effect with the steel plate and the pavement (when the lower layer is paved with SMA) is poor. Solvent-based adhesives are used in between, and the bonding performance between them is difficult to meet the design requirements
At the same time, a large amount of volatilized solvents during construction is not conducive to environmental protection and there is a risk of fire

Embodiment

[0050] as attached figure 1 As shown, the present invention constitutes a complete bridge deck pavement layer with a waterproof adhesive layer 2, a sand-grain asphalt concrete layer 3, a modified emulsified asphalt adhesive layer 4 and a surface anti-skid wear layer 5 laid in sequence on the steel bridge deck 1. The structure, specific implementation steps and technical requirements are as follows:

[0051] 1. Anti-skid structural surface setting: as attached figure 2 As shown, the eight-point welding process is adopted on the steel bridge deck 1, and the punched and rolled cross-shaped steel bar shear member 6 is set. The specification width×length×thickness of the cross-shaped steel bar shear member 6 is 5mm×50mm ×5mm, each row of cross-shaped steel bar shear members is arranged at a distance of 300mm in the curved direction and 200mm in the radial direction, and the centers of adjacent cross-shaped steel bar shear members in two adjacent rows are staggered 150mm rear arr...

Abstract

The invention discloses a high-performance steel bridge deck paving structure, and belongs to the technical field of bridge deck pavement. The high-performance steel bridge deck paving structure comprises a paving layer, wherein the paving layer is paved on a steel bridge deck plate, the high-performance steel bridge deck paving structure is characterized in that a water-proof bonding layer is arranged between the paving layer and the steel bridge deck plate, and a plurality of cross-shaped steel bar shearing resistant components are fixed on the steel bridge deck plate. Compared with the prior art, the high-performance steel bridge deck paving structure disclosed by the invention utilizes the effective combination of reconstruction of a rough surface of a steel bridge deck, a water-proof system and the paving layer to obtain the steel bridge deck paving structure which is convenient to produce, easy to compact and good in water-proof effect, planeness, interlaminar bonding force, skid resistant property and fatigue resistant property, and the high-performance steel bridge deck paving structure can be widely used for new construction and maintenance engineering of various steel bridge decks.

Description

technical field [0001] The invention relates to a bridge deck pavement technology, in particular to a high-performance 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. [0003] 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: [0004] (1) The pouring asphalt concrete (Gussasphalt) scheme represented by Germany...
