Abstract
A composition for the fixation of hydrocarbons from contaminated oily soil. The contaminated oily soil is a component in a cold mix asphaltic concrete. The soil is mixed with asphaltic roof cuttings and mineral aggregates to form the mixture. The mixture is coated with a cold mix emulsion to form an asphaltic concrete. The hydrocarbons do not leach from the set concrete.
