Cement concrete bridge floor composite pavement structure

Abstract

The invention discloses a cement concrete bridge floor composite pavement structure. The cement concrete bridge floor composite pavement structure comprises a bridge deck slab (4), wherein erection bas (5) are erected on the bridge deck slab (4), a reinforcing steel bar screen (6) is arranged on the erection bars (5), a light polymer cement concrete transition layer (3) is poured on the bridge deck slab (4), the reinforcing steel bar screen (6) is located inside the light polymer cement concrete transition layer (3), longitudinal and horizontal anti-skidding grooves (2) are formed in the upper surface of the light polymer cement concrete transition layer (3), and a bituminous concrete pavement layer is paved on the upper surface of the light polymer cement concrete transition layer (3). The cement concrete bridge floor composite pavement structure has the advantages that the service life is prolonged.

Description

technical field [0001] The invention relates to a bridge deck pavement structure, in particular to a cement concrete bridge deck composite pavement structure. Background technique [0002] Because the problem of bridge deck pavement is the junction area between the bridge and the road, it has been neglected by the two professions for many years. The current "Code for Design of Highway Asphalt Pavement" mainly provides guidance on the materials, methods and thickness of asphalt pavement structures, but does not mention specific design methods. Therefore, roads and bridges are currently designed according to their own requirements and cognitions, and no unified norms and standards have been formed. Up to now, the design and construction are still based on the knowledge of previous experience. [0003] With the rapid increase of traffic volume and heavy vehicles, especially in recent years, the phenomenon of overloading is serious, and the damage of concrete bridge deck paveme...

AI Technical Summary

Problems solved by technology

This not only hinders traffic safety, but also affects the aesthetics of the bridge deck. Some bridges on major traffic routes are particularly difficult to divert traffic, which seriously affects traffic. It also brings great difficulties to maintenance work, causing direct and indirect huge economic losses. loss
