Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Such as figure 1 As shown, the steel bridge deck composite pavement structure of the present invention includes a waterproof bonding layer 2 , an ECO modified polyurethane concrete pavement layer 3 and an ECO modified asphalt surface layer 4 . Among them, the waterproof adhesive layer 2 is coated on the bridge deck steel plate 1, the ECO modified polyurethane concrete pavement layer 3 is laid on the waterproof adhesive layer 2, and the ECO modified asphalt surface layer 4 is laid on the ECO modified polyurethane concrete pavement on layer 3.

[0033] The waterproof adhesive layer 2 is an ECO modified polyurethane waterproof adhesive layer with a thickness of 100-1000 μm. It is painted with ECO modified polyurethane waterproof paint, and the dosage is 0.1-1.0L / ㎡. ECO modified polyurethane waterproof coating includes ECO modified polyu...

Abstract

The invention discloses a steel bridge deck composite pavement structure and pavement method, A steel bridge deck composite pavement structure comprises a waterproof adhesive layer, an ECO-modified polyurethane concrete pavement layer, an ECO-modified asphalt pavement layer coated on a bridge deck steel plate, an ECO-modified polyurethane concrete pavement layer paved on the waterproof adhesive layer, and an ECO-modified asphalt pavement layer paved on the ECO-modified polyurethane concrete pavement layer. The pavement structure has excellent pavement performance and super durability, Moderatemodulus of elasticity, force balance, can improve the overall rigidity of the bridge deck system, improve the fatigue life of steel deck and pavement life, has a certain depth of construction, has good waterproofing, super-strong adhesion performance, can provide enough anti-sliding, wear and vibration and noise reduction effect. The pavement method has the advantages of low environmental requirements, relatively low engineering cost, convenient construction, easy quality control, and low environmental protection and consumption.

Description

technical field [0001] The invention relates to a road pavement structure, in particular to a full-life composite pavement structure and a pavement method for steel bridge decks with both road performance and durability. Background technique [0002] Under the existing material and technical conditions, "steel bridge" is the best structure for bridge engineering construction to achieve fast, light, shockproof, factory-like, and large-scale. However, the steel deck pavement technology has seriously restricted the development of steel bridges and even the entire bridge industry. my country, like other countries in the world, spends a lot of manpower and material resources on this research. The core of steel bridge deck pavement technology lies in the two aspects of pavement concrete material and interface bonding performance. At present, the commonly used technical solutions in China can be mainly attributed to the following categories: the earliest used double-layer SMA pav...
