Abstract
Several methodologies are available for the remediation of contaminated soils including bioremediation, vapor extraction, chemical fixation, incineration and direct disposal. A proven innovative and cost effective alternative for the fixation of contaminated soils is via cold-mix Environmentally Processed Asphalt (EPA). EPA methodology utilizes contaminated soil as an ingredient in an industrial process to produce a commercially viable product. Petroleum hydrocarbon and metal affected soil is incorporated with an asphalt emulsion and aggregate to produce a range of cold-mix asphalt product that fulfills the requirements of a variety of end uses. This viable and creative use which is within the intent and spirit of current regulations is producing, in lieu of a landfill waste, an end product for use as a berm, road base, liner, or other site specific application. Consideration of certain factors including durability, chemical resistance and ageing, biological resistance, permeability, and leachability suggests that cold-mix asphalt incorporation of affected soil will perform more than adequately under normal conditions for a long period of time.
