Embodiment 1

[0055] The construction method of the asphalt paving structure of the cement concrete bridge, including the following steps:

[0056] (1) Milling, shot shot or cutting hair treatment of cement concrete bridges, and cleaning and cleaning. The roughness of the bridge deck is determined by the sand laying method to be 0.7mm.

[0057] (2) Spray the waterproof adhesive layer of non -adhesive wheel emulsion asphalt on the processed cement concrete bridge surface Ⅰ4. The intelligent sprinkler sprinkle is used to ensure that the sprinkler is uniform, and the amount of sprinkle is 0.9kg / m. 2 Essence

[0058] (3) After the construction of the waterproof adhesion layer is completed and the emulsification is completely breaking, the multi -functional layer 3 is paved. The asphalt mixture of the multi -functional layer 3 is asphalt, 90 parts of the thickness, 4.6 parts and 0.4 copies of the compound modified asphalt. Composition of Xuanwu Rock Fiber.

[0059] Multi -functional layer 3 hybrid m...

Abstract

The invention belongs to the technical field of road engineering, and particularly relates to a cement concrete bridge deck asphalt pavement structure and a pavement construction method. According to the cement concrete bridge deck asphalt pavement structure, a waterproof bonding layer I, a multifunctional layer with the thickness of 40-80 mm, a waterproof bonding layer II and an ultra-thin wearing layer with the thickness of 15-25 mm are sequentially arranged from the cement concrete bridge deck to the top. Compared with the prior art, the asphalt pavement structure for the bridge floor can effectively improve the skid resistance and durability of asphalt pavement of the cement concrete bridge floor and prolong the service life of the structure, and has good popularization and application values.

Description

Technical field [0001] The invention is a technical field of road engineering, which involves a concrete concrete bridge asphalt paving structure and paving construction method. Background technique [0002] With the rapid development of my country's transportation construction, the requirements of highway levels have gradually increased, and the proportion of bridge project construction has also increased. As an important part of the bridge engineering, the bridge pavement mainly plays the role of protecting the bridge structure, distributed wheels, and the role of driving functions. [0003] Different from ordinary road -based road paving, due to the characteristics of the structure of the bridge deck, the paving of the bridge surface is directly paved on the bridge panel, so that the surface of the bridge pavement structure is completely exposed to the natural environment, and it is suffered from all year round. The influence of light, rain, snow, ice, and air. Compared with t...
