Embodiment Construction

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, detailed description will be given below in conjunction with the accompanying drawings.

[0020] The present invention forms a complete bridge deck pavement structure with an adhesive layer 1 , a cast-in-place layer 2 , a waterproof layer 3 , a bridge deck pavement layer 4 and a carbon fiber heating element 5 . Wherein, the bonding layer 1 is formed by blending thermoplastic polymer material, curing agent and aggregate in a certain proportion and order.

[0021] Thermoplastic polymers are high molecular polymers that soften when heated, solidify when cooled, and can be softened again. Thermoplastic polymers are plastic when heated and softened, and return to a solid state when cooled. This phenomenon can be repeated alternately, so it can be recycled and reused. Thermoplastic polymers may be, for example, polyethylene, polypropylene, polystyrene, polyurethane, and the like...

Abstract

The invention discloses a bridge deck pavement structure. A bonding layer (1), a cast-in-place layer (2), a waterproof layer (3) and a bridge deck pavement layer (4) are sequentially paved on the bridge deck pavement structure from bottom to top, a carbon fiber heating unit (5) is arranged in the bonding layer (1) in a buried mode, and the bonding layer is prepared from a thermoplastic polymer material, a curing agent and an aggregate. By using the prepared bridge deck pavement structure, a large amount of operation for chiseling away a concrete cast-in-place layer can be omitted, the problem that a main beam structure is damaged in the chiseling process is solved, the noise pollution and the water pollution in the chiseling construction are avoided, and the bridge deck pavement structure has good application and popularization values.

Description

technical field [0001] The invention relates to a bridge deck pavement structure, which belongs to the field of architectural design. Background technique [0002] Bridge deck pavement refers to the protective layer paved on the bridge deck, which is an important part of the bridge structure. to the effect of spreading loads. The quality and durability of bridge pavement will directly affect the driving quality and durability of the car. [0003] In recent years, with the increasing size and weight of bridge-crossing vehicles and the rapid growth of traffic volume, the impact of vehicles on bridge components and the frequency of stress exceeding have also increased, which has a greater impact on component fatigue. This makes the bridge deck pavement in an extremely severe state of use, and the bridge deck pavement has cracks, wrapping, rutting, cracking, falling off and other damage phenomena, which not only hinders traffic safety, but also affects the beauty of the bridge...
