Problems solved by technology

[0002] With the development of urban roads, based on the pavement defects of the original urban roads, sponge roads are developed and used, which are extremely water-permeable, allowing rainwater to flow into the ground, effectively replenishing groundwater, and alleviating the urban environmental problems of the city's sharp drop in groundwater levels, and It can effectively eliminate the hazards of environmental pollution such as oil compounds on the ground. At the same time, it is also an excellent pavement material for protecting groundwater, maintaining ecological balance, and alleviating the urban heat island effect. It is conducive to the healthy development of human living environment and urban Rainwater management and water pollution prevention and control are of special significance. The construction of sponge cities is also going on. However, the strength of traditional cement-based materials is low, and it is difficult to obtain double guarantees for performance and water permeability. The service life is short and it is easy to produce Cracking, for this purpose, we propose a nano-inorganic polymer permeable pavement performance enhancer
