Asphalt pavement composite structure and construction method thereof

Abstract

The invention provides an asphalt pavement composite structure and a construction method thereof. One side of a pavement sequentially comprises an asphalt upper face layer, an asphalt lower face layer, an asphalt pavement base course and an embankment structure from top to bottom, the other side of the pavement sequentially comprises a concrete pavement layer, a concrete pavement base course and an embankment structure from top to bottom; and first filling bodies are arranged among the asphalt upper face layer, the asphalt lower face layer and the concrete pavement layer, second filling bodiesare arranged among the asphalt lower face layer, the asphalt pavement base course and the concrete pavement base course, and elastic filling bodies are arranged between the asphalt upper face layer and the concrete pavement layer. According to the asphalt pavement composite structure, through arrangement of the first filling bodies, the second filling bodies, the elastic filling bodies, a first deformation coordinating plate, a second deformation coordinating plate, an elastic joint layer and vertical bearing piers, the influences of temperature stress and differential deformation on a road structure can be effectively prevented and controlled, and a crack reflection channel is blocked.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an asphalt pavement composite structure and construction method that can effectively prevent and control the influence of temperature stress and differential deformation on road structures and effectively block crack reflection channels. Background technique [0002] With the rapid development of urban construction in our country, residents have higher and higher requirements for the performance of roads, and often encounter road reconstruction and expansion problems, and connection problems of different pavement materials or structures. Constrained by material strength, density, bearing capacity, etc., contact cracks often appear at the joints between asphalt pavement structures and other pavement structures. The infiltration channel and stress concentration release area of ​​the water body are formed, which seriously affects the mechanical performance, durability an...

AI Technical Summary

Problems solved by technology

The pavement structure achieves the purpose of delaying the occurrence of reflective cracks on the pavement to a certain extent, but it does not involve the waterproof and drainage problems at the joints, which is prone to water damage.

[0004] To sum up, the existing pavement structure and construction technology have achieved certain construction effects under suitable working conditions, but there is room for improvement in improving the integrity of the pavement structure, reducing stress concentration at joints and sudden changes in stiffness.
