Title: SALVAGING PETROLEUM-CONTAMINATED SOILS FOR HIGHWAY CONSTRUCTION
Accession Number: 00723798

Availability: Find a library where document is available Abstract: Excavated petroleum-contaminated soil (PCS) from leaking underground storage tanks can either be disposed of in landfills or decontaminated--by bioremediation and low-temperature desorption--and used in the highway industry as construction material. This article presents the results from an extensive laboratory and field study in New Jersey, sponsored by the New Jersey Department of Environmental Protection, that was conducted to evaluate the feasibility of using PCS in the production of hot-mix asphalt. This study proved that remediated PCS can be used to produce hot-mix asphalt concrete suitable for highway pavement, and enabled the New Jersey Department of Transportation (NJDOT) recycling task force to conclude that up to 20% of the soil may be added to bituminous-stabilized base course or used as a soil aggregate, as long as the soil complies with the aggregate quality and gradation requirements of the NJDOT 1989 standard specification for hot-mix asphalt. The use of PCS in hot-mix asphalt has also proved economical. Adding 5% of the PCS to a mix can save the producer $0.45 per metric ton of hot-mix asphalt by replacing virgin aggregate, which costs approximately $9 per metric ton. If a solid-waste disposal cost of $100 per metric ton is factored in, an additional $5 is saved per metric ton of asphalt produced.
