Problems solved by technology

Over the past ten years, we have gone through the initial stage of exploration and the stage of digestion and absorption of imported technology. At present, engineers and technicians have a deep understanding of the reasons for the success or failure of steel bridge deck pavement, as well as the advantages and disadvantages of imported technologies from Britain, the United States, Japan and other countries. A deep understanding and some improvements have been made, but my country still lacks innovative structures and complete sets of technologies with independent intellectual property rights

Embodiment 1

[0011] Embodiment 1: ① Sandblast and derust the bridge deck steel plate 1 to make it reach Sa2.5 level, and the roughness reaches 80 μm; 2 The standard scraping epoxy resin sizing material constitutes the epoxy bonding layer 2 immediately; 3. after the epoxy bonding layer 2 is scraping, sprinkle the small crushed stones 31 with a particle diameter of 4mm immediately, so that the small crushed stones 31 are bonded on the An epoxy bonded gravel layer 3 is formed on the epoxy bonded layer 2, and the ratio of the area occupied by the small gravel 31 to the area of ​​the epoxy bonded layer 2 is 80%; A cold-mix resin asphalt concrete layer 4 with a thickness of 2.5 cm is laid above the layer 3, so that small crushed stones 31 are embedded in the cold-mix resin asphalt concrete layer 4. 12mm single-grain gravel 41 with an area ratio of 5% is spread on the upper surface of the upper surface, and the single-grain gravel 41 is partially embedded in the cold-mix resin asphalt concrete la...

Embodiment 2

[0012] Embodiment 2: 1. Sandblast and derust the bridge deck steel plate 1 to make it reach Sa2 level, and the roughness reaches 60 μm; 2 The standard scraping epoxy resin sizing material constitutes the epoxy bonding layer 2 immediately; 3. after the epoxy bonding layer 2 is scraping, sprinkle the small crushed stones 31 with a particle diameter of 3mm immediately, so that the small crushed stones 31 are bonded on the An epoxy bonded gravel layer 3 is formed on the epoxy bonded layer 2, and the ratio of the area occupied by the small gravel 31 to the area of ​​the epoxy bonded layer 2 is 75%; A cold-mix resin asphalt concrete layer 4 with a thickness of 2.0 cm is laid above the layer 3, so that small crushed stones 31 are embedded in the cold-mix resin asphalt concrete layer 4. 12mm single-grain gravel 41 with an area ratio of 5% is spread on the upper surface of the upper surface, and the single-grain gravel 41 is partially embedded in the cold-mix resin asphalt concrete lay...

Embodiment 3

[0013] Embodiment 3: ① Sandblast and derust the bridge deck steel plate 1 to make it reach Sa3 level, and the roughness reaches 100 μm; 2 Scrape the epoxy resin sizing material to form the epoxy bonding layer 2 immediately; 3. sprinkle the small crushed stones 31 with a particle diameter of 5mm immediately after the epoxy bonding layer 2 is scraped, so that the small crushed stones 31 are bonded on the An epoxy bonded gravel layer 3 is formed on the epoxy bonded layer 2, and the ratio of the area occupied by the small gravel 31 to the area of ​​the epoxy bonded layer 2 is 85%; A cold-mix resin asphalt concrete layer 4 with a thickness of 1.5 cm is laid above the layer 3, so that small crushed stones 31 are embedded in the cold-mix resin asphalt concrete layer 4. 12mm single-grain gravel 41 with an area ratio of 5% is spread on the upper surface of the upper surface, and the single-grain gravel 41 is partially embedded in the cold-mix resin asphalt concrete layer 4 through a ru...

Abstract

The invention discloses a steel bridge deck pavement structure comprising an epoxy bonding layer coated on a steel bridge deck, and an epoxy bonding gravel layer which comprises a layers of gravels with grain diameter of 3 to 5 mm and equally arranged on the epoxy bonding layer, wherein the area ratio between the gravel area and the epoxy bonding layer is 65 percent to 85 percent; and a cold-mixed resin asphalt concrete layer with thickness of 1.5 to 3.0 cm is paved on the epoxy bonding gravel layer to lead the gravels to be embedded into the cold-mixed resin asphalt concrete layer; and gravels with single grain-diameter of 10 to 13 mm and with the area ratio of 5 to 10 percent are embedded on the upper surface of the cold-mixed resin asphalt concrete layer and part of the gravels projects out of the surface thereof; an asphalt concrete surface functional layer with thickness of 4 to 6 cm is paved on the cold-mixed resin asphalt concrete layer and part of the single-diameter gravels are embedded into the asphalt concrete surface functional layer; and a waterproof asphalt layer is coated between the asphalt concrete surface functional layer and the cold-mixed resin asphalt concretelayer. The invention has the advantages that quality is reliable; construction is convenient; cost is lower; and maintenance is convenient.

Description

technical field [0001] The invention relates to a road surface pavement structure, in particular to a steel bridge deck pavement structure and a pavement method. Background technique [0002] Steel bridge deck pavement is a worldwide problem, and countries all over the world spend a lot of manpower and material resources on researching it. With the construction of more and more long-span steel bridges in our country, the asphalt concrete pavement of the steel bridge deck, as a special engineering technical problem, urgently needs a proper solution. At present, the domestic technical solutions for steel bridge deck pavement can be classified into two categories: one is the double-layer epoxy asphalt concrete pavement technology introduced from the United States, and the other is the poured asphalt concrete pavement technology introduced from the United Kingdom. These two types of technologies have some successful experience in foreign countries, but the cost is high. Under t...
