Abstract
The present invention is directed to a waste or environmental containment system that includes modified asphalt specifically designed for containment, and a system of installation that provides a seamless cap over the area to be contained. The modified asphalt of the present invention has a permeability less than 1×10−8 cm/sec and an air void content less than 3 percent. The system of installation includes joint designs that meet the same parameters as the modified asphalt mat to provide a seamless containment cap or liner to contain hazardous wastes at RCRA, Superfund sites, waste sites and environmental containment areas.
Claims1
A joint for an asphalt paving mat having permeability less than 1×10−5 cm/sec comprising:
- a first panel having a first edge and a second edge, the first edge having a first thickness and the second edge having a thickness less than the first thickness such that the panel has a tapered cross sectional thickness;
- modified asphalt on a top surface of the first panel;
- a second panel overlaying the first panel, the second panel having a reciprocal tapered cross sectional thickness wherein the combination of the first and the second panels provides a constant thickness;
- and
- a membrane anchored between the first and the second panels wherein the membrane further includes at least one of a window, the window providing an area of bonding contact between the first panel and the second panel.
