Asphalt batching, a stabilization/solidification method
for treating hydrocarbon-contaminated soils, incorporates
petroleum-laden soils into hot asphalt mixtures as a partial
substitute for stone aggregate. This mixture can then be
utilized for paving. This process involves excavation of the
contaminated soils, which then undergo an initial thermal treatment, followed by incorporation of the treated soil into
an aggregate for asphalt. During the incorporation process,
heating of the mixture results in the volatilization of the
more volatile hydrocarbon constituents (Asante-Duah,
1996). The remaining compounds are incorporated into an
asphalt matrix during cooling, thereby limiting constituent
migration. After it is given sufficient time to set and cure, the
resulting solid asphalt now has the waste uniformly
distributed throughout it and is impermeable to water
