Highway pavement structure and construction method thereof

Abstract

The invention discloses a highway pavement structure and a construction method thereof. The highway pavement structure comprises a gravel leveling layer, a cement stabilized soil subbase layer arranged on the upper surface of the gravel leveling layer, an anti-collapse net rack, a cement stabilized macadam base layer, a concrete cushion layer, an epoxy asphalt layer; the anti-collapse net rack is arranged in the cement stabilized soil subbase layer and is fixedly connected with the cement stabilized soil subbase layer; the cement stabilized macadam base layer is arranged on the upper surface of the cement stabilized soil subbase layer; the concrete cushion layer is arranged on the upper surface of the cement stabilized macadam base layer; and the epoxy asphalt layer is arranged on the upper surface of the concrete cushion layer. The vertical load is converted into part of horizontal thrust through a steel bar wave-shaped grating net, the pressure bearing capacity of the highway pavement is improved, and thus the problems that a surface layer structure of an existing highway pavement structure is single, the bearing capacity of the surface layer structure mainly depends on the quality of materials, and the structure for improving the strength is not provided are effectively solved.

Description

technical field [0001] The invention relates to the technical field of pavement structures, in particular to a highway pavement structure and a construction method thereof. Background technique [0002] The pavement structure layer refers to the paving layers that make up the pavement. According to their layers and functions, they mainly include surface layer, base layer and subbase layer. The latest "Code for Design of Highway Asphalt Pavement" points out that the pavement structure layer is composed of three parts: surface layer, base layer and subbase layer. The previous cushion layer can be classified as functional layer or subgrade disposal layer. The pavement not only bears the load of the wheels, but also is affected by natural environmental factors. Due to the influence of traffic load and atmospheric factors on the pavement, it generally weakens gradually with depth, so the pavement is usually a multi-layer structure. Good quality materials are laid on the upper l...

AI Technical Summary

Problems solved by technology

[0003] The surface structure of the existing highway pavement structure is relatively simple, and its bearing capacity mainly depends on the quality of the materials used, and there is no structure to improve the strength from the structure
