ABSTRACT:
This invention relates to a method for producing asphalt that has improved low temperature properties. More specifically, the penetration and Penetration Index of an asphalt can be increased if the asphalt is heat soaked in the presence of a dehydrogenation agent at a temperature above the temperature at which oxidation of the asphalt occurs and below the temperature at which coking is initiated. Polyvinyl chloride and a chlorinated wax are preferred dehydrogenation agents.
