Porous asphalt allows water to drain through the asphalt and into the stone bed below. It then works its way into the soil as nature intended. If toxins are on the surface, they get swept along with the rainfall through the stone bed. From there, they travel into the sub-base so that they are subjected to the natural processes that cleanse water. The size and depth of the stone bed must be designed so that the water level never rises into the asphalt.
