Description

technical field

[0001] The invention relates to a pavement structure, in particular to a permeable pavement structure with good ecological benefits. Background technique

[0002] In recent years, a large number of roads have been built in various cities across the country, which greatly facilitates people's travel and promotes the development of our country's economy. But because urban road basically all adopts impermeable hardened pavement (promptly " cementized " pavement), also brought a lot of traffic and environmental problems to the city.

[0003] Because the road surface is not permeable to rainwater, the replenishment of groundwater by rainwater is blocked. Since the city collects groundwater exceeding the standard every year, if the rainfall cannot be replenished in a timely and effective manner, a land subsidence zone will be formed, which will cause serious damage to geology and buildings. Huge damage. The hardened pavement will also bring serious harm to the ec...
