Durable cement concrete bridge deck pavement structure with noise reduction and water drainage functions

Abstract

The invention discloses a durable cement concrete bridge deck pavement structure with noise reduction and water drainage functions. A high-performance cold-paved waterproof bonding layer is arranged on the upper surface of a treated concrete bridge deck, the high-performance cold-paved waterproof bonding layer is paved with durable high-modulus asphalt concrete, a waterproof layer is arranged on the upper surface of the durable high-modulus asphalt concrete, and the upper surface of the waterproof layer is paved with an anti-skidding noise reduction and water drainage wear thin layer. The modulus of the asphalt concrete is increased through the durable high-modulus asphalt mixture, deformation of the road surface structure under the effect of vehicle loads is relieved, high-temperature deformation resistance of the road surface is improved, and generation of ruts is delayed. The high-performance waterproof bonding layer material is adopted, attention is paid to treatment of the concrete bridge deck, and bonding durability of the waterproof layer, an asphalt pavement surface layer and a cement concrete board is improved. Noise of the road surface can be lowered to a certain degree through the anti-skidding noise reduction and water drainage wear thin layer, water accumulated on the road surface is eliminated, driving safety is improved, and good social benefits are achieved.

Description

technical field [0001] The invention relates to a bridge deck pavement structure, in particular to a durable cement concrete bridge deck pavement structure with noise reduction and drainage functions. Background technique [0002] Bridge deck pavement refers to the protective surface layer paved on it to ensure that vehicles pass through the bridge deck safely and comfortably, and is an important part of the bridge structure. Its function is to prevent the wheels from directly wearing the roadway slab, protect the main girder from the erosion of rainwater and other harmful substances, and play a role in spreading the load. The quality and durability of bridge deck pavement will directly affect the driving quality of cars and the durability of bridge structures. At present, cement concrete bridges generally adopt the pavement system of double-layer asphalt concrete pavement + waterproof bonding layer. After more than ten years of scientific research, modified asphalt SMA, ep...

[0003] However, with the increasing demand for road surface performance in modern traffic, people also put forward higher requirements for road safety, comfort, environmental protection and resource reuse. Although a variety of bridge deck pavement structures have been proposed, but The durability, anti-skid, drainage, noise reduction, and wear resistance of the bridge deck structure still cannot meet the requirements of use
