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.
Claims5
A method of constructing a porous pavement structure capable of capturing hydrocarbon contaminants carried by rain water comprising:
- applying a layer of recycled glass over a soil surface;
- compacting the applied layer of recycled glass to a modified Proctor of at least 90%;
- applying a fabric or mesh over the compacted layer of recycled glass;
- applying a structure containing a plurality of open-top grid pockets having rigid or semi-rigid upwardly-extending vertical grid walls for receiving and holding a wearing course composition;
- filling the grid pockets with a wearing course composition comprising a mixture of recycled glass, aggregate and flexible resin binder;
- and
- curing the adhesive binder.
