Embodiment 1

[0032] A water-permeable pavement leveling layer material, comprising 80 grams of epoxy resin, 5000 grams of fine gravel stone particles with a particle size of 0.5-10mm discontinuously graded and 20% of coarse sand. The permeable pavement leveling layer material is formed by curing epoxy resin, gravel stone fine particles and coarse sand. The grade of epoxy resin is E51, the viscosity at 25°C is 12000mPa·s, and the epoxy value is .51.

Embodiment 2

[0034] A water-permeable pavement leveling layer material comprises 102 grams of acrylic resin and 1700 grams of fine gravel stone particles with a particle size of 1-12 mm. The permeable pavement leveling layer material is formed by mixing and curing acrylic resin and gravel stone fine particles. The grade of acrylic resin is 1321, and the viscosity at 25°C is 5Pa·s.

Embodiment 3

[0036] A water-permeable pavement leveling layer material comprises 150 grams of polyurethane resin and 7,500 grams of fine gravel stone particles with a particle size of 15 mm. The permeable pavement leveling layer material is formed by mixing and curing polyurethane resin and gravel stone fine particles. The polyurethane resin is selected from the two-component polyurethane resin disclosed in Chinese patent CN 104004490 B.

Abstract

The invention provides a brand new pervious pavement total-pervious leveling layer material and a total-pervious pavement structure, and belongs to the field of municipal engineering and building. The leveling layer material comprises a high-molecular adhesive and aggregate which are mutually mixed, wherein the aggregate comprises stone particles and / or grits, the stone particles and the grits are single particles or are discontinuously graded, and the stone particles have high porosity and good water permeability; and the high-molecular adhesive has better adhesion stress, extensibility and freeze thaw resistance than previous binders which are cement and lime. The leveling layer material and the pavement structure are different from pervious pavement leveling layer materials adopting cement and sands, or sands and lime sands, or pure sands, and corresponding pervious pavement structures, have the characteristics of total-pervious property of the integral pavement, high water permeability, strong adhesion stress, strong compressive strength and good freeze-thawing resistance, are helpful for realizing an integral structure between the upper layer and the lower layer of a pavement, are durable and can realize a total-pervious effect.

Description

technical field [0001] The invention relates to the fields of municipal engineering and construction, in particular to a brand-new fully permeable leveling layer material for a permeable pavement and a fully permeable pavement structure. Background technique [0002] With the continuous development of my country's economy, urbanization continues to advance. However, at the same time as rapid urbanization, the urban hardening area is increasing, and urban development is also facing huge pressure on the environment and resources. Therefore, it is necessary to coordinate the contradiction between urbanization and environmental resource protection in order to achieve sustainable development. Sponge city has attracted more and more attention because of its concept of natural accumulation, natural infiltration and natural purification. Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural di...
