Composite pavement structure of steel bridge deck and paving method of composite pavement structure

Abstract

The invention discloses a composite pavement structure of a steel bridge deck. The composite pavement structure comprises a bottom waterproof bonding layer, a lower paving layer, a top bonding layer and a top paving layer. The bottom waterproof bonding layer, the lower paving layer, the top bonding layer and the top paving layer are sequentially paved on the steel bridge deck. The lower paving layer is made of epoxy asphalt concrete, and the top paving layer is made of asphalt concrete. The composite pavement structure has the advantages of both asphalt concrete and stone mastic asphalt (SMA) concrete, construction cost can be reduced, service life can be prolonged, and maintenance period can be shortened.

Description

technical field [0001] The invention relates to the field of bridge deck pavement, in particular to a composite pavement structure of a steel bridge deck and a pavement method thereof. Background technique [0002] In recent years, my country's bridge industry has developed rapidly, and more and more long-span steel bridges have been built. As an important part of the bridge structure system, the bridge deck pavement plays an extremely important role in the durability and safety of the bridge. However, at present, there is still no perfect and mature technical solution in the technical field of steel bridge deck pavement in our country. [0003] At present, the pavement materials used for steel bridge decks in my country are mainly epoxy asphalt concrete or SMA asphalt concrete (asphalt mastic macadam mixture). Due to its high strength, epoxy asphalt concrete can thin the pavement layer and reduce its own weight. At the same time, it has excellent durability, chemical corr...

Problems solved by technology

[0005] A technical problem to be solved by the present invention is to overcome the defects that the existing steel bridge deck pavement material adopts epoxy asphalt concrete with poor skid resistance, high price and difficult maintenance, while adopting other SMA asphalt concrete is easy to be damaged, and proposes a A composite pavement structure of a steel bridge deck and a pavement method thereof, the composite pavement structure is easy to maintain, and has the good
