DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a water permeable unit and a road surface structure using the same.

[0002]

2. Description of the Related Art Glass recovered as waste is crushed, and a part of the glass is used as a recycled glass for living decoration, or used as a car stop or asphalt mixed material. Currently, most of them are left unloaded. This is because the surface of the ground glass is sharp and inconvenient to handle. In order to eliminate this obstacle, the surface of the ground glass material is also worn, but the abrasion processing is troublesome and leads to an increase in material cost, and thus the reuse of the recovered glass has not been advanced. Also, discarded tires are the same as discarded glass, and discarded tires are used as fuel during cement production or used as recycled tires, but since the amount that can be reused is limited, almost all Have been left unstacked, and the danger of fire has been pointed out. Therefore, there is a long-awaited need to convert waste glass and waste tires into construction materials that can be reused in large quantities.

On the other hand, in a residential area, in particular, in a site where a plurality of apartment houses are built, a drain ditch or a catchment basin is provided for treating rainwater falling on the site. Since the ditch and catchment basin require relatively large land, there is a problem from the viewpoint of effective use of land.

[0004]
