Title: EVALUATION OF SOLVENTS FOR EXTRACTION OF RESIDUAL ASPHALT FROM AGGREGATES
Accession Number: 00622187
Record Type: Component
Availability: Find a library where document is available Abstract: When highway cores and hot mixes are extracted, several percent of the asphalt frequently remains on the aggregate. A variety of solvents were evaluated for their ability to remove this material. They were compared using several aggregates that had been extracted by three procedures. The effectiveness of alcohols as a solvent additive was investigated. Finally a direct comparison of trichloroethylene and toluene containing 15% ethanol using an old road-core material was made. In general, trichloroethylene containing 15% ethanol was the best solvent tested. Pyridine is similar but objectionable for other reasons. The residual unextracted material is difficult to remove even with the best solvents.
