It is estimated by the United States Environmental Protection Agency (USEPA) that there are 2 to 3.5 million underground storage tanks (USTs) throughout the nation and about 25% of these tanks are leaking. The leakage of petroleum or other organic material presents serious environmental problem due to the uncontrolled release of petroleum products to ground water. Many new techniques have developed to reuse these petroleum contaminated soils generated from sites containing leaking USTs. One such soil reuse method available since 1985 is the use of petroleum contaminated soils in the production of hot mix asphalt.

The stability, durability, and hydraulic conductivity are three important engineering parameters that need to be considered when using petroleum contaminated soils (PCSs) in hot mix asphalt (HMA). In three separate theses, the stability, durability of asphalt concrete mixed with PCSs and the environmental impacts of the process were investigated. In this thesis, the variation in hydraulic conductivity due to the addition of PCSs in to HMA is investigated.

The hydraulic conductivity of Hot Mix Asphalt pavement affects its performance. However, there are no publications that document the hydraulic conductivity of hot mix asphalt concrete made with or without petroleum contaminated soils. In this thesis, six different hot mix asphalt concrete mixes with petroleum contaminated soils and a control mix were designed and the hydraulic conductivity were measured. The measured hydraulic conductivity values are then correlated to the properties of the matrix in the HMA concrete.
