USE OF DIESEL-CONTAMINATED SOIL IN RECYCLED COLD-MIX PAVEMENT

The U.S. military, working with State and the EPA, combined a contaminated asphalt cement and a reclaimed asphalt pavement (RAP) to produce an asphalt paving material suitable to contain diesel-contaminated soil. The project involved the use of various contaminated and waste materials, including a diesel contaminated soil, a stockpile of ashpalt cement, and a stockpile of RAP. These materials were combined and stabilized with an emulsified asphalt cement to produce an improved roadway pavement. Prior to construction, analysis was conducted to find if the asphalt mixture containing the contaminated soil would leach petroleum materials. Toxicity characteristic leaching procedure extract tests on mixtures with and without contaminated materials demonstrated that leaching of unacceptable levels of contaminated materials would not occur under lab-simulated conditions. The use of these materials in paving construction allows for substantial cost savings over costs required for the removal and disposal of such materials. These contaminated materials provided a sound structural base for construction of pavement, with a test roadway performing satisfactorily since its placement 4 years ago.
