Low Solvent Emulsified Asphalt Study

摘要

The objective of the study was to develop a low solvent, stockpilable, bituminous pavement patching material. Foamed asphalt and aromatic oil with emulsified asphalt were studied as binders with virgin aggregates. Although low solvent, these were found to have unsatisfactory stockpile characteristics. Foamed asphalt and rejuvenating agents were studied to produce a pavement maintenance material from recycled asphalt pavement. Neither of these efforts were successful. Unique Paving Mixture (UPM) produced by Sylvax Corporation specifications and currently in use by Arizona Department of Transportation was examined and found to meet the properties of a low solvent pavement patching material.
