Embodiment Construction

[0015] as attached figure 1 As shown, multiple composite paving materials of the present invention are jointly applied to the technical method of paving the deck of a highway steel bridge, and its structure includes an adhesive layer 2, a bulk material 3 and a roll material 4. The adhesive layer 2 is a spray paint with waterproof, anti-rust, stable physical and chemical properties, and strong adhesion with the steel bridge deck 1. The coiled material 4 is a sheet-like pavement material composed of inorganic, high-strength, and low-elastic filament braids as the supporting grid 5 and polyurethane asphalt concrete as the filler 6, which can be rolled and spread. Bulk material 3 is modified asphalt concrete with more coarse aggregate, more mineral powder, more asphalt and less fine aggregate.

[0016] During construction, the steel bridge deck 1 is derusted and cleaned, the spray coating is evenly and tightly sprayed, and cured to form an adhesive layer 2, the paving coil 4 is c...

Abstract

The invention relates to a technical method for paving road steel bridge decks by combined applications of various composite paving materials. The technical method comprises an adhesive layer, a coiled material and bulk materials. The technical method is characterized in that the adhesive layer, the coiled material and the bulk materials are paved and tamped successively and hierarchically, wherein the adhesive layer is a spraying coating which are waterproof and rustproof and has strong adhesion to the rigid bridge deck; the coiled material is a sheet and windable spread paving material which is formed by using inorganic, high-strength, low elastic knitted fabric as a support grid structure and polyurethane asphalt concrete as a filling material; and the bulk materials are modified asphalt concrete with much coarse aggregate, slag, asphalt and little fine aggregate. Compared with a conventional method, the technical method provided by the invention is characteristics of waterproof and anti-corrosion protection steel bridge deck, synergetic reinforced bridge deck rigidity, anti-extension, anti-shift and anti-breakage, difficult appearance of delamination, cracks, tracks and pushed piles, antifatigue, aging resistance and the like. Besides, the technical method has the advantages of strong industrial production adaptability, less materials, low cost, simple repair and maintenance, etc. Therefore, the technical method has very good prospects for popularization and applications.

Description

1. Technical field: [0001] The invention relates to road steel bridge deck pavement, in particular to a technical method for joint application of multiple composite pavement materials to pave the road steel bridge deck. 2. Background technology: [0002] The flow of people and logistics that support economic vitality, along with the rapid development of the social economy, requires an increasingly large and diverse number, mode and speed of its channels. Highway steel bridges play an increasingly important role in providing channel shortcuts and flow, while The reliability, stability and durability of steel bridge deck pavement are the most direct and obvious elements to ensure the function of steel bridge. The steel bridge deck pavement under the prior art mainly adopts pavement materials such as hot-mix asphalt concrete, modified asphalt concrete, cast asphalt concrete, epoxy resin asphalt concrete, etc., and is completed by single-layer or double-layer pavement. The abov...
