Abstract
A water-pervious pavement structure comprising wearing course comprising a water-pervious combination of recycled glass and aggregate bound together with a flexible adhesive binder and held within a plurality of connected, open grid pockets; and a layer of unbound recycled glass disposed under the wearing course capable of adsorbing contacting hydrocarbons carried with water through the wearing course. In a preferred embodiment, the wearing course comprises about 30 wt. % to about 80 wt. % recycled glass and about 20 wt. % to about 70 wt. % aggregate bound together by a cured resin binder within the grid pockets.
Claims15
A water-pervious pavement structure comprising:
- (a) wearing course comprising a water-pervious combination of recycled glass particles and aggregate particles bound together with a flexible adhesive binder and held within a plurality of connected, open grid pockets;
- (b) a layer of unbound recycled glass disposed directly under the wearing course capable of adsorbing contacting hydrocarbons carried with water through the wearing course;
- and
- (c) a caisson or aperture excavated under the layer of unbound recycled glass to a depth below a frost line to achieve a thermal moderating effect resulting from air rising, through said aperture and into said unbound recycled glass layer.
