Magic glue creates a “breathing” road surface

Every summer when there is heavy rain, many cities will suffer from drainage problems The problem of "seeing the sea" caused by poor traffic, just imagine, if our road surface can be strongly permeable to alleviate the crisis of "seeing the sea" in rainy days, and the road surface will naturally evaporate water vapor to alleviate the city's "heat island effect" on sunny days, wouldn't it be great? Reporter From Suzhou High-tech Zone Bobang Rubber Industry Co., Ltd., we have seen this new type of road surface system - Yisutou.

This is a permeable pavement paved by mixing natural granite stones with a special glue. Fang Hong, general manager of Bobang Adhesive Company, showed a model to reporters. In the transparent model box, there is a layer of natural cobblestones at the bottom, and coarse stones on top. The surface layer of the road is built with adhesives produced by Bobang and natural granite gravel to form a stable open structure, which is poured continuously by water pumps. Water from the "pavement" is penetrating these materials, creating an "aquifer" beneath the pavement. What's even more amazing is that aquatic plants are also planted in the aquifer to raise fish.

"This new type of pavement system is permeable and breathable, and its anti-rainfall capacity can reach twice the red warning of heavy rain, that is, when the rainfall reaches more than 100mm within 3 hours, the pavement will not generate runoff." Fang Hong said. It is understood that this magic glue has become an important new material for the construction of sponge cities. Zheng Yinsheng, technical director of Bobang Company, said: "The pavement made of our polyurethane permeable pavement material has good water retention and porosity. The water permeability can reach 3 times that of traditional materials, and the flexural rate can reach 2.5 times. Heat island effect, lower temperature and noise, maintain urban ecological balance.”

The staff told the reporter that the environmental protection of pavement materials has passed SGS testing and certification, and the construction is in full compliance with international indoor environmental protection standards, and does not contain harmful volatiles such as formaldehyde. It is reported that the construction of this new type of pavement is very convenient. Each worker can lay 100 square meters per day. Large areas can also be operated continuously by machinery. People can leave within 2 to 3 hours after construction, and its cost is only as high as that of traditional asphalt permeable pavement. And 70%~80% of concrete permeable pavement.
