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.
