Long-life pavement structure for steel bridge deck and pavement method of pavement structure

Abstract

The invention discloses a long-life pavement structure for a steel bridge deck and a pavement method of the pavement structure. The long-life pavement structure comprises an anti-corrosion layer, a lower adhesive layer, a lower gravel layer, a structural layer, an upper adhesive layer, an upper gravel layer and a wearing layer which are sequentially arranged on the steel bridge deck from bottom to top. The pavement structure has excellent antiskid and waterproof performances, low-temperature cracking resistance, high-temperature rutting resistance, fatigue resistance and water stability, is fine in deformation compatibility with a steel plate and wear-resistant, surface aggregates do not easily fall off, the pavement method of the pavement structure is high in mechanization degree and strong in feasibility, the paved steel bridge deck can be put into operation in a short time, only the wearing layer of the pavement structure is damaged, only regular surface milling and top facing repair are needed, the pavement structure does not need to be structurally reconstructed in a long service life period, maintenance is facilitated, maintenance cost is saved, and the pavement method conforms to the design concept of a long-life pavement and also conforms to the energy conservation and environmental protection concept of modern society.

Description

technical field

[0001] The invention belongs to the technical field of bridge deck engineering, and relates to a long-life pavement structure for a steel bridge deck and a pavement method thereof, in particular to a steel bridge with both anti-skid performance and waterproof performance, low-temperature performance and high-temperature performance Long-life pavement structure and pavement method for surface. Background technique

[0002] The pavement structure for the steel bridge deck is the protective layer of the steel bridge deck and the functional layer that directly provides services to users. It plays an important role in the durability of the bridge, driving safety, comfort, and economic and social benefits. Compared with ordinary road pavement structures, the pavement structures for steel bridge decks have the following characteristics: (1) The pavement structures for steel bridge decks are generally located in traffic throats, and the traffic pressure is relatively...
