METHOD OF DISPOSAL OF HAZARDOUS PARTICULATE SOLID WASTE BY ASPHALT EMULSION ENCAPSULATION

摘要

A method of disposing of hazardous particulate waste containing hazardous waste ions comprises forming an asphalt emulsion slurry containing the waste and using the slurry as a commercial asphalt emulsion slurry seal. The method comprises the steps of: a) selecting an emulsifying agent suitable to form a stable emulsion of asphalt, water and said particulate waste; b) mixing the particulate waste and asphaltic emulsion in proportions to form an asphaltic emulsion slurry having safe leaching properties; c) utilizing said asphaltic emulsion slurry in existing commercial uses. The particulate waste may be ash from incinerators containing unsafe levels of lead.
