Our company is a modern enterprise engaged in developing and producing colored asphalt, selling and secondhand trading with asphalt mixing plant, leasing Road equipment, pavement design and construction, and producing and selling colored asphalt concrete and color permeable concrete. With the development of social economy and city construction process, the surface of the modern city gradually covered the building of reinforced concrete and impermeable pavement, compared with natural soil, modern surface caused a series of problems to the city, which mainly manifested in the following aspects:
First, impervious roads inhibit the infiltration of rainwater, which makes the compensation for groundwater to be interrupted, plus the excessive extraction of groundwater.
Two, the appearance of the traditional dense road, the big noise of the tire. When the vehicle is running at high speed, it will press the air into the tire and the road surface when the tire rolls in. When the tire rolls over, the air will expand and declare the noise, especially in rainy days, which will affect the life and operation of the residents.
Three, the traditional urban road surface is impermeable structure, the rain through the road surface cleaning, the discharge is limited, when encountering heavy rain or rainstorm, the rainwater is simply collected on the road surface, many of them converge on the motor vehicle and the bicycle lane, causing the road surface large-scale water accumulation.
Four, no ecological water permeable concrete reduces the air humidity in the city, and adds the composition of urban heat island effect immediately.
Five, the non ecological pervious concrete is the "dead ground", which will affect the ecosystem on the ground. It makes the water ecosystem unable to circulate properly, breaking the balance of the urban ecosystem and affecting the normal growth of vegetation.
For a variety of short should not ecological permeable concrete, some developed countries such as the USA and Japan began to research using pervious concrete pavement, and used in the square, pedestrian street, road and on both ends of the base isolation zone, the park journey and parking lot, to increase the city's permeable to water and air space of city microclimate, scheduling adhere to the ecological balance plays a good role, has been known as the "breathing concrete pavement", "ecological color pavement". The countries represented by Japan and the United States are the most preemptive countries and regions in the research and application of permeable concrete pavement materials in the world.
