Rural waste cement concrete road renovated pavement structure and filling method thereof

Abstract

The invention discloses a pavement structure for renovating and transforming a rural waste cement concrete road and a filling method of the pavement structure. The pavement structure comprises an asphalt surface layer, a graded broken stone layer and a regenerated broken stone layer which are arranged above a soil matrix from top to bottom, v-shaped regenerated gravel drainage ditches are formed in the two sides of the regenerated gravel layer and filled with regenerated gravel; road shoulders are arranged on the two sides of the pavement structure and extend from the asphalt surface layer to the recycled gravel drainage ditch; and plant fiber grids surround the periphery of the graded broken stone layer. According to the invention, the rural waste cement concrete road pavement material is fully utilized to form the regenerated gravel layer and the regenerated gravel drainage ditch, so that the pollution to the environment is reduced, the waste material is fully utilized, and the road drainage can be further accelerated. The application of the plant fiber grating effectively enhances the structural strength of the pavement, reduces the generation of various cracks, and improves the quality of the asphalt pavement, thereby prolonging the service life of the asphalt pavement, reducing the maintenance cost of the road, optimizing the comprehensive benefits of road operation, and having important significance for promoting the development of rural economy.

Description

technical field [0001] The invention belongs to the field of road pavement structures, and relates to a method for repairing road pavement structures, in particular to the refurbishment and reconstruction of rural waste cement concrete roads and a filling method thereof. Background technique [0002] Since the cement concrete pavement has the advantages of high strength, mature road construction technology, and low investment, cement concrete pavement has been widely used in rural areas of my country since the 1970s and 1980s. However, with the increasing traffic demand in rural areas, a large number of cement concrete roads have problems such as broken boards, mud, and potholes, which can no longer meet the requirements of economic development for the rapidity, safety and comfort of roads. Renovate these old cement concrete roads. [0003] Two methods are often used for the renovation of cement concrete roads, namely: [0004] (1) Excavate all the original road surface by...

Problems solved by technology

This transformation method increases the cost of transportation and raw material purchase. If the milling waste is not properly disposed of, it will become construction waste and cause environmental pollution.

[0005] (2) Pave the asphalt mixture surface directly on the original cement concrete pavement, but as time goes by, reflection cracks of the original cement pavement will appear on the new pavement, and the generation of reflection cracks will cause water seepage on the pavement, thus making the A large number of diseases appear on the newly transformed road surface, which shortens the service life of the transformed road surface and affects traffic
