What is the effect of permeable surface on urban pavement?

First, the main organic component in the runoff of environmental protection parking lot is hydrocarbons (oil) in the asphalt binder of parking lot itself, which often pollutes the environment. Because the breathable floor is composed of porous honeycomb structure, it can adsorb these substances harmful to the environment well. Second, it is not necessary to easily maintain the problem of pore blockage that people are worried about. The unique permeable floor pavement can solve this problem only by washing with high-pressure water. 3. The permeable terraces with high water permeability have pores of 15%-25%, which can make the water permeability reach 31.18-51.96 l/m/h, which is much higher than the drainage rate of the most effective rainfall under the optimal drainage configuration. It can quickly and effectively eliminate urban road surface water. Fourth, excellent freeze-thaw performance The pavement technology of permeable ground is advanced, which has stronger freeze-thaw resistance than ordinary pavement and will not be broken due to freeze-thaw, because its structure itself has large pores. V. High bearing capacity Appraised by national testing institutions, the bearing capacity of permeable floor can completely meet the bearing standard of C30 concrete, which is higher than that of ordinary permeable bricks. 6. Durability The durability and wear resistance of permeable floor are better than asphalt and close to ordinary concrete, which avoids the shortcomings of short service life and uneconomical common permeable brick. Its life can be as long as 30 years. Seven. A good aesthetic transparent floor has a color scheme, which can cooperate with the designer's creativity and realize the decorative style required by different environments and personalities. This is difficult for ordinary permeable bricks to do.
