Abstract
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.
Claims14
A road surface covering system, comprising:
- a road surface covering comprising at least one of concrete or asphalt, the road surface covering being define by a first outer edge;
- a plurality of water permeable tiles disposed adjacent to the first outer edge of the road surface covering, the water permeable tiles having a water conductivity, based on a constant water column of 30 inches, of at least 7 inches of water per hour;
- and
- a subgrade bed of fill material disposed beneath the plurality of water permeable tiles and at least a portion of the road surface covering, the subgrade bed of fill material comprising a porous sand, the porous sand comprising at least 70% by weight of a naturally occurring micaceous arkose rock material, the micaceous arkose rock material comprising at least 30% by weight of mica, at least about 50% by volume of the micaceous arkose rock material having a mean diameter of between about 0.060 mm and about 0.65 mm, and the micaceous arkose rock material having been previously kilned at of temperature of between 1100° C. and 1250° C. to transform at least 30% by weight of micaceous components in the micaceous arkose rock material into feldspar containing metal sulfides.
