US 7,077,602 B2 · Method and system for containment, such as a containment cap for solid waste constructed of modified asphalt

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.

Claims12

Dependent claims

A seamless containment system comprising:

a mat of modified asphalt concrete having an air void content less than 6%, permeability coefficient, k, less than 1×10−5 cm/sec and a resilient modulus of less than 3000 MPa;
and
at least one of an installation joint, the joint having a first cold panel and a second overlapping hot panel wherein modified liquid asphalt is placed between the first and the second panels during installation binding the first and the second panels.

Dependencies are inferred from the claim text.
