Poirer, M A

This patent describes a paving grade asphalt composition having an ASTM penetration value of at least 85 at 25/sup 0/C and a solubility in trichloroethylene of at least 99.0% comprising at blend of: (a) petroleum pitch having a boiling point above 524/sup 0/C obtained as a residue in the hydrocracking of hydrocarbon oils to a pitch conversion of at least 80% and containing up to 10% by weight saturates, about 10-30% by weight aromatics, about 15-30% by weight resins and about 30-55% by weight asphaltenes and (b) as a diluent, an unprocessed distillation residue has a minimum initial boiling point of 370/sup 0/C obtained from a bitumen from tar sands, or heavy oils. The pitch is present in the composition in an amount of at least 25% by weight of the total composition.
