Embodiment Construction

[0010] The green plant-growing permeable asphalt concrete of the present invention is composed of porous asphalt concrete and a planting matrix, and the planting matrix includes water, nutrient solution, tall fescue seeds or bermudagrass seeds, phalanx powder, sodium carboxymethyl cellulose, and the proportioning of its mass ratio For, water: nutrient solution: tall fescue seeds or bermudagrass seeds: lanstone powder: sodium carboxymethylcellulose=70~86 / 4~8 / 1~5 / 6~12 / 3~5;

[0011] Nutrient soil can also be added in the above material, and the proportioning of its mass ratio is, water: nutrient solution: tall fescue seed or bermudagrass seed: lanstone powder: nutrient soil: sodium carboxymethyl cellulose=70~86 / 4~8 / 1~5 / 6~12 / 6~8 / 3~5.

[0012] The mixed planting matrix adopts the method of infiltration or injection to fill the internal voids of porous asphalt concrete with a porosity of 20% to 26% to form plant-grown porous asphalt concrete. Plants can grow directly on its surface...

Abstract

The invention relates to a green plant growth permeable pitch concrete and its preparing method, relating to a technical method for preparing environmental protection green road surface layers of city parks and life estates. Its composition: the mass ratio of water to nutrient solution to seeds of tall fescue / bermudagrass to rectangular stone powder to carboxymethyl cellulose sodium is (70-86) : (4-8) : (1-5) : (6-12) : (3-5); filling the mixed planting substrate into the pores inside the porous pitch concrete with porocity of 20%-26% to form the plant growth permeable pitch concrete. Its preparing method: firstly preparing a mixed solution of nutrient solution and water in a specified proportion; successively preparing the planting substrate, i.e. uniformly blending the rectangular stone powder, nutrient earth and seeds of tall fescue, pouring the prepared planting substrate into the mixed solution in batches, adding in carboxymethyl cellulose sodium thickening agent and blending uniformly, and finally making the uniform planting substrate permeate into or injected into the surface layer of the porous pitch concrete.

Description

technical field [0001] The invention relates to a preparation technical method of an environmentally friendly green road surface layer suitable for various parking lots in urban areas and sidewalks in living quarters, and belongs to the field of preparation and research and development of new environmentally friendly high-performance building materials. Background technique [0002] Ground parking is almost the main way of parking in urban residential areas in my country. This type of parking lot has a single function and usually uses a concrete floor, which has problems such as strong heat radiation, large dust, and impervious ground. In recent years, ecological parking lots have appeared, that is, to increase the greening rate of the parking lot, consider the parking landscape, and improve the ecological environment of the residential area. The common ecological parking lot, that is, the parking lot paved with lawn bricks, generally has the problems of insufficient pressu...
