Large-span steel box beam bridge deck pavement layer material gradient structure pavement construction method
The invention discloses a large-span steel box beam bridge deck pavement layer material gradient structure pavement construction method. The method comprises the steps that 1, derusting by sandblast and cleaning processing are conducted on an interface of a steel bridge deck; 2, shearing force parts are welded between a steel plate and a concrete pavement layer; 3, steel rib meshes are paved, and the steel rib meshes are bound to the shearing force parts; 4, high-strength toughening light concrete is poured; 5, a DPS waterproof layer is sprayed; 6, a bond stress absorbing layer is paved; 7, high-viscosity high-elastic SMA-13 bituminous mixtures are paved. According to the large-span steel box beam bridge deck pavement layer material gradient structure pavement construction method, polymers and fibers are added, the light aggregate concrete mix proportion design is optimized, the strength, the toughness, the deformability and the anti-fatigue performance of the light aggregate concrete are strengthened, and an optimal design on the arrangement of the shearing force studs and the steel rib meshes and the reinforcement ratio is conducted.
