Problems solved by technology

[0002] As a well-known technology in this field, the traditional concrete pavement is a pavement structure with high rigidity, strong spreading load stress capacity, good stability and long service life. Compared with other pavements, it has the following advantages: high strength, stable Good performance, good durability, low maintenance cost, good anti-skid performance, and good for driving at night; but it also has the following disadvantages: large demand for cement, high construction technology requirements, slow construction progress, late opening to traffic, difficult maintenance and repair
The patent claims in the beneficial effect that the bonding strength is high, and it is economical and environmentally friendly, but there is no data to prove its high strength, and there is no way to study the water permeability of the patent

Embodiment 1

[0042] A water-permeable pavement, which includes a surface layer 1 and a glue-stone concrete layer 2 from top to bottom; the surface layer 1 is formed by integrating fine aggregate and a first binder covering the fine aggregate, and the glue The stone concrete layer 2 is integrated by the coarse aggregate and the second binder covering the coarse aggregate. The fine aggregate is quartz sand, D 50 =0.01~0.25cm, the particle size distribution range is 0.005~0.08cm; the coarse aggregate D 50 = 0.3 to 0.55 cm, and the particle size distribution range is 0.1 to 0.8 cm; the Mohs hardness of the fine aggregate is above grade 8, and the Mohs hardness of the coarse aggregate is above grade 6.

[0043] The first binder is epoxy resin containing a curing agent, and the second binder is a mixture of heat-conducting glue and cement. The curing agent of the epoxy resin is a polyamide resin, and the mass ratio of the epoxy resin to the polyamide resin is 1:1.

Abstract

The invention relates to a pavement, and in particular relates to a permeable pavement and a construction method thereof. The permeable pavement sequentially comprises a surface layer and a glue stone coagulating layer from top to bottom, wherein the surface layer is formed by fine aggregate and a first binding agent through integration, the glue stone coagulating layer is formed by coarse aggregate and a second binding agent clad with the coarse aggregate through the integration, the first binding agent is epoxy resin containing a curing agent, the second binding agent is a mixture of thermal conductive clay and cement, the first binding agent and the second binding agent both contain pore-foaming agents which take a mixture of polyvinyl alcohol and polyvinyl alcohol pyrrolidone as main ingredients, and the pore-foaming agent accounts for 10-20% of the epoxy resin or the thermal conductive clay in using amount. The strong binding capability of the epoxy resin, the cement and the clay is utilized to ensure the compressive strength of the pavement, and the pore-foaming agent and an air entraining agent are arranged on the water and air levels, so that the relatively strong water permeability and air permeability of the pavement are achieved.

technical field [0001] The invention relates to a pavement, in particular to a permeable pavement and a construction method thereof. Background technique [0002] As a well-known technology in this field, the traditional concrete pavement is a pavement structure with high rigidity, strong spreading load stress capacity, good stability and long service life. Compared with other pavements, it has the following advantages: high strength, stable Good performance, good durability, low maintenance cost, good anti-skid performance, and good for driving at night; but it also has the following disadvantages: large demand for cement, high construction technology requirements, slow construction progress, late opening to traffic, and difficult maintenance and repair. Therefore, it is usually used in the construction of airports. Traditional concrete pavement also has the disadvantage of poor water permeability. [0003] As a well-known technology in the field, asphalt is a dark brown ...
