A road surface covering system includes a road surface covering of concrete or asphalt, water permeable tiles disposed adjacent to an outer edge of the road surface covering and having a water conductivity of at least 7 inches of water per hour, and a subgrade bed of fill material including a porous sand. The porous sand includes at least 70% of a naturally occurring micaceous arkose rock material having at least 30 wt % of mica, and at least 50 vol % of the micaceous arkose rock material having a mean diameter of between 0.060 mm and 0.65 mm. The micaceous arkose rock material being previously kilned at a temperature of between 1100° C. and 1300° C.
