Abstract

The invention provides a construction method of a steel bridge deck slab laid lower layer and relates to the technical field of steel bridge deck slab construction. The method includes the following steps that multiple steel plates are laid to form a steel plate base layer; a pouring type bituminous concrete material is laid on the steel plate base layer, so that a base layer of the laid lower layer is formed; and gravel is scattered to the base layer of the laid lower layer, so that the laid lower layer is formed. The technical problems that modified asphalt SMA is adopted as a laid lower layer of a steel bridge deck in the prior art, so that the sealing performance, the waterproof performance and the watertight performance are poor are solved, and the technical effects of the good sealing performance and the good waterproof performance are achieved.

Description

technical field [0001] The invention relates to the technical field of steel bridge deck construction, in particular to a construction method for paving a lower layer of a steel bridge deck. Background technique [0002] At present, the common pavement of steel bridge deck adopts modified asphalt SMA (asphalt mastic macadam mixture produced by using modified asphalt), epoxy resin pouring asphalt concrete material and roller compacted asphalt mastic concrete. Among them, the content of coarse aggregate in modified asphalt SMA is as high as 70%, the content of mineral powder is about 10%, and the amount of asphalt is 6%-7%. In order to prevent the leakage of modified asphalt SMA during mixing and transportation A certain amount of fiber stabilizer is usually added to the modified asphalt SMA. Modified asphalt SMA has the advantages of strong flexibility, strong anti-loosing and strong crack resistance, and has good durability and waterproof performance, strong resistance to p...
