An asphalt blend in which a butadiene-styrene elastomeric block polymer can easily be dispersed at between about 325°F. and about 400°F. and, after cooling, forms a stable material useful as a roofing composition and having a flash point of greater than about 450°F., said blend consisting essentially of a propane extracted asphalt, said propane extracted asphalt having been prepared by mixing an asphaltic petroleum flux with propane, with or without other solvents, and allowing the mixture to separate into layers and collecting the propane extracted asphalt from the bottom layer, and from about 5 weight % to about 45 weight % of a fluid bed catalytic petroleum cracker bottoms oil comprising a major proportion of oils boiling above 700°F. and, optionally, a minor proportion of oils boiling between about 350°F. and 700°F.
