Compared with concrete, pervious concrete pavement With the development of social economy and urban construction, the surface of modern cities is gradually covered by reinforced concrete house buildings and impervious pavements. Compared with natural soil, modern surface brings cities to the city. A series of problems are mainly manifested in the following aspects:
(1) Impervious pavements impede the infiltration of rainwater, making the supplementation of rainwater to groundwater blocked, coupled with the excessive extraction of groundwater, the urban ground is prone to subsidence.
(2) The surface of the traditional compact road has large tire noise. During the high-speed driving of the vehicle, when the tire rolls in, it will push air into the space between the tire and the road surface. When the tire rolls over, the air will rapidly expand and make noise. This kind of noise is especially noticeable in rainy days, which affects the lives and work of residents.
(3) Pervious Concrete The traditional urban road surface is impervious to the structure. Rainwater is discharged through the road surface and the discharge capacity is limited. When heavy rain or heavy rain is encountered, rainwater is easily collected on the road surface and concentrated on the roads of motor vehicles and bicycles, resulting in large roads. Range of water.
(4) The impervious pavement reduces the humidity of urban air and accelerates the formation of the urban heat island effect.
(5) Impervious pavement is a "dead surface", which affects the ecosystem of the ground. It makes the water ecology unable to circulate properly, breaking the balance of the urban ecosystem and affecting the normal growth of the vegetation.
