Cement water-permeable concrete ground structure with water-permeable asphalt on surface and manufacturing method thereof

Abstract

The invention discloses a cement water-permeable concrete ground structure with water-permeable asphalt on the surface. The structure comprises components of, from top to bottom: an asphalt water-permeable concrete layer, a spacer layer, a cement water-permeable concrete layer, a bedding layer and a base layer. A manufacturing method of the ground structure comprises steps that: (1) the base layer is paved; (2) the bedding layer is paved on the base layer; (3) at least one cement water-permeable concrete layer is paved on the bedding layer; (4) a water-permeable spacer layer is paved on the surface of the cement water-permeable concrete layer, and is optional; and (5) at least one asphalt water-permeable concrete layer is paved on the cement water-permeable concrete layer or the spacer layer. The manufacturing method also comprises a step (6), which is a maintenance step. The cement water-permeable concrete ground structure with the water-permeable asphalt on the surface is an environment-friendly ground structure.

Description

technical field [0001] The invention relates to a cement permeable concrete ground structure with permeable asphalt on the surface and a manufacturing method thereof, which belongs to the technical field of road surface paving. Background technique [0002] The pavement materials of municipal motor vehicle roads only have cement concrete pavement and asphalt concrete pavement. At present, there are permeable cement concrete and permeable asphalt concrete on the market, but due to their respective limitations, it is difficult to directly apply them to municipal motor vehicles. Cement permeable concrete has the characteristics of high load capacity, high water permeability, ecological environmental protection, replenishment of groundwater, reduction of urban heat island effect, high safety in rainy and snowy weather, and natural and simple appearance. However, permeable asphalt concrete also has high Bearing capacity, high water permeability, etc., but because of its semi-rig...

AI Technical Summary

Problems solved by technology

At present, there are permeable cement concrete and permeable asphalt concrete on the market, but due to their respective limitations, it is difficult to directly apply them to municipal motor vehicles.

Cement permeable concrete has the characteristics of high load capacity, high water permeability, ecological environmental protection, replenishment of groundwater, reduction of urban heat island effect, high safety in rainy and snowy weather, and natural and simple appearance. However, permeable asphalt concrete also has high Bearing capacity, high water permeability, etc., but because of its semi-rigid characteristics, rainwater cannot directly infiltrate and replenish groundwater; at the same time, due to its rigid material, cement permeable concrete needs to be cut off as a whole for repair when it encounters damage. It is not very convenient to repair
