Embodiment 1

[0013] The construction method of the plant crushed stone pavement comprises the following steps: a. laying a graded crushed stone layer with a thickness of 20 centimeters; Good material; c, be 10% by weight percentage and prepare the planting soil mixture, wherein the planting soil mixture contains 20% organic fertilizer; d, mix the prepared gravel and the planting soil mixture, and carry out Test the sprinkling water so that its water content is 9.8%; e, transport the evenly mixed mixture to the site, and pave it with a paver or a grader, and the paving thickness is 25 cm; f, the spreading weight percentage is 0.2% Hound 5# grass seed; g, rolling with 8 tons of road rollers, the degree of compaction is 90%, and the thickness after compaction is 20 cm; h, through sprinkling and maintenance until the grass seed germinates.

Embodiment 2

[0015] The construction method of plant crushed stone pavement comprises the following steps: a, laying a graded crushed stone layer according to a thickness of 25 centimeters; Good material; c, be 8% by weight percentage and prepare the planting soil mixture, wherein the planting soil mixture contains 15% organic fertilizer; D, mix the prepared crushed stone and planting soil mixture, and carry out Sprinkle water and test to make the water content 8.5%; e, transport the evenly mixed mixture to the site, and pave it with a paver or a grader, and the paving thickness is 25 cm; f, the weight percentage of spreading is 0.5% g, rolling with a 7-ton road roller, the degree of compaction is 95%, and the thickness after compaction is 15 cm; h, through watering and maintenance until the grass seeds germinate.

Embodiment 3

[0017] The construction method of plant crushed stone pavement comprises the following steps: a. laying a graded crushed stone layer according to a thickness of 15 centimeters; C, be 9% by weight percentage and prepare the planting soil mixture, wherein the planting soil mixture contains 10% organic compound fertilizer; D, mix the prepared gravel material and the planting soil mixture, and carry out Test the sprinkling water so that its water content is 5.8%; e, transport the evenly mixed mixture to the site, use a paver or a grader to pave, and the paving thickness is 25 cm; f, spread the weight percentage of 0.2% Bagengrass grass seeds; g, rolling with an 8-ton road roller, the degree of compaction is 90%, and the thickness after compaction is 10 cm; h, watering and curing until the grass seeds germinate.

Abstract

The invention relates to a plant gravel road surface, and its characteristic: the road surface has two layers, the base layer has step-distributed gravels and the surface layer has gravels and plant earth mixture where the surface layer is composed of set-distributed gravels, plant earth mixture, grass seeds and water in weight percents of 80-88%, 6-18%, 0.1-1% and 5-13%, respectively, the base layer is 10-30 cm thick and the surface layer is 10-25 cm thick. It has 100% of greening rate and higher bearing capacity of road surface, suitable for park, square road surface and footway road surface. It has good water permeability, low thermal radiation, natural environmental protection, etc. it has the advantages of simple structure, low cost, quick field construction, and short time.

Description

Technical field: [0001] The invention relates to a road or a terrace pavement, in particular to an ecological pavement or an ecological pavement of a parking apron or a square in highways, municipal projects and the like. Background technique: [0002] In highway and urban road engineering, road surface problems will be encountered. At present, the usual pavement structure is asphalt concrete pavement or cast-in-place cement concrete pavement or masonry (including prefabricated block) pavement. Especially when used as parking apron (square) and sidewalk, generally also will adopt bituminous concrete pavement or cast-in-place cement concrete pavement or masonry (comprising prefabricated block) pavement. Although the hardened pavement is neat and durable, its biggest disadvantage is that it is impermeable. The road surface is impermeable, so that the replenishment of groundwater by rainwater is completely blocked during rainfall, making it difficult for the groundwater level...
