Investigation of Alternative Solvents for Asphalt Extraction and Recovery

In October 2023, the United States Environmental Protection Agency announced an impending ban on trichloroethylene (TCE). TCE is a widely used solvent that can dissolve many organic materials, including asphalt binder. The objectives of this research are as follows. Identify potential alternative solvents to TCE. Assess the benefits and drawbacks of each. Develop solvent extraction protocol using the most promising solvent. Evaluate extracted binder (using the selected solvent) for characterization. Quantify the variability between recovered binder and that of TCE extracted and original asphalt binders. Introduce an optimum approach to utilize the new technique if feasible.
