Background
In the process of urban development, the requirement on urban pavements is higher and higher, and the urban pavements are gradually replaced by cement asphalt pavements from the original mud pavements. The cement asphalt pavements are usually made of water-blocking materials, and the water impermeability of the pavements cuts off the natural circulation process of water, so that the original natural ecological background and hydrological characteristics are changed. On one hand, the change can promote the reduction of surface water infiltration, thereby causing urban waterlogging; on the other hand, the supplement of underground water can be influenced, and the ecological balance of the surrounding environment is potentially broken; furthermore, overly-hardened urban paving is a key factor contributing to the urban "heat island effect". The constant expansion of urban water-impermeable decking changes the energy balance of the earth's surface, allowing for elevated near-surface temperatures, and also for reduced relative humidity in urban areas by affecting near-surface water vapor flux and temperature.
The pervious asphalt concrete material is a novel green environment-friendly material, is prepared by taking coarse aggregates, fine aggregates, mineral powder and asphalt as basic raw materials, has higher porosity, can quickly remove water accumulated on a road surface, reduces the generation of water films on the road surface and water drift of a driving, and simultaneously has the function of reducing noise; in addition, the automobile seat cushion has larger surface roughness, and the safety and the comfort of driving are enhanced. The popularization and the application of the pervious asphalt concrete material bring great ecological effect, safety effect and social benefit, and the pervious asphalt concrete material can become a main building material of a road pavement. The pervious asphalt concrete has large void ratio and low strength.
