Problems solved by technology

[0002] The plastic pavement has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. However, the existing plastic track will experience performance degradation, partial damage, and reduced stability after a period of use.
In particular, the water permeability of the existing runway or pavement is not good, and the accumulation of the pavement surface is more likely to cause damage to the pavement surface
As the market has higher and higher requirements for the environmental protection performance of products, ordinary silicon PU materials have certain volatility.
Especially under the sun exposure and high temperature, it is prone to the problem of continuous volatilization of harmful gases, which seriously affects human health

Abstract

The invention relates to the technical field of materials, and relates to a using, pavement laying and preparation method of a material, in particular to a permeable pavement adhesive and a using method thereof. The permeable pavement adhesive is suitable for an adhesive stone permeable pavement because an adhesive layer is high in strength, high in toughness, good in yellowing resistance and strong in adhesion after cured. The product has excellent wear resistance, weather resistance and aging resistance. The increase in use amount of stone further reduces the use amount of volatile organic compounds. The permeable pavement adhesive is good in fluidity, can be fully mixed with the stone to ensure the strength after laid, is good in construction performance, excellent in performance-priceratio, outstanding in wear resistance, strong in aging resistance and high in mechanical strength, is ensured to be unchanged in performance for a long time after construction, and solves the defectsof cracking, deformation and the like in extremely high and low-temperature weather.
