greenbiz Ground is a pavement block made by molding granular microporous ceramics as aggregate to increase strength. The water retention capacity has been greatly improved to 1.5 times or more of the conventional water retention block. It has excellent water permeation performance and it is difficult for puddles to form, making it the perfect material for places where people gather.
It has been recognized that it has plenty of rainwater and cools the road surface with a water spray effect. The difference is 5 ~ 20 ℃ compared to normal asphalt pavement. Contributes to alleviating the heat island phenomenon and creating a comfortable environment.
When laying Green Biz, water pools are less likely to occur due to its water absorption capacity.
Once the water has been absorbed, it is retained inside, and when it reaches the full saturated water content, it is allowed to permeate the roadbed and subgrade. The effect is exhibited in rainwater runoff control and permeable storage.
The air layer contained in the small holes in the aggregate functions as a heat insulating layer. Even in the freezing state confirmation test (-20 ° C), it has been confirmed that both the surface and the interior are hard to freeze and the frictional resistance is maintained. In addition, the freeze-thaw test has cleared 150 cycles (6 times the standard), and is also recommended in cold regions.
