Highway pavement rubblization treatment and reuse laying construction structure and technology

Abstract

The invention discloses a highway pavement rubblization treatment and reuse laying construction structure and technology and belongs to the field of road construction. The construction structure comprises an original roadbed and a pavement cushion layer. The pavement cushion layer is formed after panel rubblization treatment and roller compaction of an original damaged pavement, and the upper portion of the pavement cushion layer is spread to form a concrete surface layer. The construction technology includes the work steps of early-stage preparation, test site setup, MHB smashing, raw material clearing, compacting and spreading, joining and the like. Investment of raw materials is saved, production cost is reduced, the whole pavement is firm in structure and high in pressure resistance, the whole engineering process is simple, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a pavement construction structure and process for paving damaged concrete pavement after gravel treatment and reuse. Background technique [0002] In the overhaul and renovation project of the old road, there are various defects in the old road before the reconstruction. For example: due to the large traffic volume and serious transportation overload, the cement pavement has many damaged slabs and local subsidence, and the pavement as a whole is exposed to wear; the pavement is uneven, and the thickness difference is large; There is a large gap in the strength of the road surface; the water content of some roadbeds is high, and problems such as lack of compactness, sinking, and looseness in some areas of the roadbed are also potential factors that cause road surface sinking, cracking, and damage. [0003] During the processing of old roads, the original road surface needs to be ...

AI Technical Summary

Problems solved by technology

[0003] During the processing of old roads, the original road surface needs to be broken and the gravel transported out of the reconstruction area before the road surface can be re-paved. This not only wastes the original pavement materials, but also increases transportation costs and increases The amount of raw materials increases the construction cost, which is not conducive to popularization and application

In addition, due to the serious disease of the old cement concrete pavement, when the broken slab rate and the average staggered amount are used to evaluate the pavement damage condition, the pavement damage condition is serious, and the old cement concrete pavement and the base layer do not have sufficient bearing capacity to support the asphalt pavement. operation, the existing paving construction structure is not enough to support the operation of the entire pavement, making the paved pavement poor in pressure bearing
