Abstract: Using hot-mix asphalt (HMA) is one answer to contaminated soil. HMA plants can be modified to accept some contaminated soil—a boon not only to the generator of the soil but the asphalt producer and to regulators concerned with disposal options. An asphalt was modified in Massachusetts. The process starts with a concrete storage area which will hold the soil. The soil passes over a scalping screen to remove large particles and then heads into a rotating ceramic cylinder inserted between the burner and the dryer. The plant was shown to successfully clean test sands loaded with oil and organic pollutants.
