Abstract

The invention discloses a fiber net-ultra high toughness cementitious compound material composite bridge deck structure and a method. The fiber net-ultra high toughness cementitious compound material composite bridge deck structure comprises a bridge deck plate and a fiber net-reinforced ultra high toughness cementitious compound material pavement layer poured onto the bridge deck plate, wherein an asphalt concrete wearing layer is paved on the fiber net-reinforced ultra high toughness cementitious compound material pavement layer. In the fiber net-ultra high toughness cementitious compound material composite bridge deck structure, due to the adoption of the fiber net-reinforced ultra high toughness cementitious compound material pavement layer, damages, such as longitudinal cracks and wave pass which are caused by repeated action of temperature and vehicle load, local upheaval and comminuted racks of the traditional asphalt concrete paving method are avoided; patency and comfort of vehicles are improved; the durability of a bridge structure is also improved.

Description

technical field [0001] The invention relates to a bridge deck composite structure, a pavement material and a construction method thereof, in particular to a fiber mesh-ultrahigh toughness cement-based composite material composite bridge deck structure and a construction method. Background technique [0002] With the rapid development of my country's economy, bridges are an important part of roads, and their mileage and proportion of roads are constantly increasing. The durability of the bridge structure and the use function of the bridge deck have also been paid more and more attention. A reasonable and reliable bridge deck pavement system can not only provide a bridge with good driving performance and durability, but also serve as an effective protection system for the bridge deck to prevent water penetration and ensure the durability of the bridge structure. At present, asphalt concrete is mainly used for bridge deck pavement of high-grade highways, but the asphalt concre...
