AbstractThe application of ambient temperature asphalt emulsion stabilization technology to the environmental fixation of soils contaminated by organic contaminants, primarily hydrocarbons, was pioneered in 1987. Since that time, the process has seen many applications in recycling contaminated soils into an environmentally stable, structurally enhanced, paving base material. A bench‐scale demonstration was undertaken to evaluate and demonstrate the effectiveness of the process in immobilizing environmental contaminants, at various concentrations, from four common petroleum products. Results of the tests presented demonstrate the degree of effectiveness of the stabilization process for soils contaminated by No. 2 Fuel Oil, No. 6 Fuel Oil, Gasoline, and Jet Fuel (JP4). The analytical parameters for which the fixation effectiveness is demonstrated include volatile organic compounds (VOCs), total petroleum hydrocarbons (TPH), and polynuclear aromatic hydrocarbons (PAHs). Descriptions of the process and details regarding the environmental and structural characteristics of the final product are presented.
