Abstract

The invention discloses a novel ultra-high-performance ECC bridge floor composite structure suitable for a steel bridge, and a construction method. The composite structure comprises a reinforcing steel bar shear resisting structure, a steel bridge panel layer arranged on the bottom layer, and an ultrahigh toughness cement composite material layer poured on the steel bridge panel layer. The reinforcing steel bar shear resisting structure is poured in the ultrahigh toughness cement-based material. A bituminous concrete wearing layer is paved on the ultrahigh toughness cement composite material layer. In the ultrahigh toughness cement-based composite material bridge floor combined structure, use of the ultrahigh toughness cement-based composite material pavement layer prevents longitudinal cracks, wavy displacement, partial upheaval, and comminuted cracks and other diseases generated by temperature and repeated action of vehicle load in conventional bituminous concrete pavement. The structure improves smooth property and comfortableness of vehicles, and has great help for improving endurance of the bridge structure.

Description

Technical field [0001] The invention relates to a steel bridge deck composite structure, a paving material and a construction method thereof, in particular to a novel ultra-high toughness cement-based composite material bridge deck composite structure suitable for steel bridges and a construction method thereof. Background technique [0002] With the construction of a large number of steel bridges, the level of steel bridge structure design and construction technology in my country has improved rapidly, but the development of bridge deck paving technology has been relatively lagging, resulting in most of the quality problems and diseases in the use of steel bridges. Paving on the bridge deck has become a weak link that affects the quality of steel bridge construction in my country. [0003] At present, most of the deck paving materials used for steel bridges are asphalt concrete, but the thermal stability of asphalt concrete is poor, and the shear strength between the asphalt paving...
