Embodiment 1

[0053] This example figure 1 As shown, it is a fatigue-resistant and rutting-resistant steel bridge deck pavement structure, which consists of a waterproof adhesive layer 1, a lower pavement layer 2, an adhesive layer 3 and an upper pavement layer 4 from bottom to top. The paving lower layer 2 is laid on the waterproof adhesive layer 1 , the adhesive layer 3 is sprayed on the paving lower layer 2 , and the paving upper layer 4 is laid on the adhesive layer 3 .

[0054] The waterproof adhesive layer 1 is an epoxy resin waterproof adhesive layer, which is composed of Japanese KD-BEP epoxy resin main agent and Japanese KD-BEP curing agent at a mass ratio of 0.5:0.5, under the temperature condition of 30±2°C After stirring for 3 minutes, spray evenly on the steel bridge deck, and the mass sprayed on the steel bridge deck is 0.9kg / m 2 , the thickness is 0.5 ~ 1.5mm. After the waterproof adhesive layer is sprayed, wait for it to solidify at room temperature for 2 to 3 hours before...

Abstract

The invention provides a fatigue-resistant and rutting-resistant steel bridge deck pavement structure and a pavement method. The steel bridge deck pavement structure is as follows from bottom to top: an epoxy resin waterproof bonding layer with a thickness of 0.5 to 1.5 mm; rubber asphalt AC-10 pavement lower layer, its thickness is 2.5~3.5cm; rubber asphalt bonding layer, its thickness is 0.3~0.5mm; rubber asphalt SMA‑13 pavement upper layer, its thickness is 2.5~3.5cm. The fatigue-resistant and rutting-resistant steel bridge deck pavement structure of the present invention has better coordination with the deformation of the steel plate. While normally meeting the road performance requirements of resisting fatigue cracks and high-temperature rutting deformation, the surface is more wear-resistant, and it is convenient for construction and Advantages of economy and environmental protection.

Description

technical field [0001] The invention relates to the technical field of pavement asphalt mixture, more specifically, to the technical field of steel bridge deck pavement structures, in particular to a fatigue-resistant and anti-rutting steel bridge deck pavement structure. Background technique [0002] Research at home and abroad shows that one of the most effective structural forms of long-span bridges (including cable-stayed bridges and suspension bridges) is a stiffened steel box girder bridge. Because the bridge deck pavement directly serves the running vehicles, its engineering quality directly affects the traffic capacity, driving safety, comfort, durability of the bridge structure, and social and economic benefits of the bridge. However, compared with other types of bridges such as cement concrete bridges and steel truss bridges, the pavement of steel box girder bridges does not have the rigid floor support of other bridges. Strict, acceptance conditions are more comp...
