ABSTRACT
A major consideration when formulating remedial action plans is the determination of what technology will best serve the specific project needs. No two projects are exactly alike, and each has site-specific limitations. However, three objectives must always be met if the reme diation project is to be successful: The remedial method must be cost-effective, time-efficient, and environmentally sound. The production of asphalt is conventional in nature and well es tablished [1]. Recycling soil containing petroleum hydrocarbons and metals affected soil via incorporation into cold-mix asphalt is a proven remedial technology [2-6]. In addition, the incorporation of affected soil into asphalt products by the process refer to as environmentally processed asphalt (EPA™) is viewed as environmentally sound and has proved to be costeffective while providing the minimal amount of long-term liability in comparison with other soil remediation options and alternatives. Affected soils, formerly classified as hazardous waste, are incorporated with asphalt emulsion and specified grades of aggregate to produce a range of cold-mix asphalt products that fulfill the requirements of a variety of end uses. Notable among these uses are landfill caps and liners; tank farm dikes and containment structures; park ing lots, truck terminal and salvage yard pavements; road construction material; and port fa cility container shipping yard surfacing.
