ABSTRACT
The primary mechanisms of remediation in this instance are volatilization and thermal destruction by incineration. Large quantities of the lighter petroleum hydrocarbons contained in gasolines, kerosenes, and fuel oils are incompatible with asphalt. The incorporation of soils containing petroleum products into asphalt mixes is not widely practiced. A review of the current literature on asphalt mixes and additives found no mention of this process. The pad and storage pile must be covered when the plant is not in operation. In theory, the high temperatures encountered by petroleum-bearing soils in the aggregate dryer should completely destroy any hydrocarbons that might be present. The strength and durability of asphalt paving mixes is dependent on the size, type, and amounts of aggregates used. Additional equipment is needed when petroleum-laden soils are utilized in an asphalt batching plant. No pre- or post-treatment is needed for soils that are incorporated into asphalt mixes.
