Asphalt blend compositions containing used motor oil and asphalt pavement compositions containing said asphalt blend compositions

An asphalt blend composition which comprises an asphalt component and a bottoms fraction obtained from used lubricating oil formulations containing base oil stock and organo-metallic component by:

• i) directly contacting said used lubricating oil with a heated vapor selected from the group consisting of methane, ethane, propane, and steam, under temperature, contact times, and superficial velocity conditions sufficient to at least partially decompose said organo-metallic component and provide a desired volume of pumpable bottoms, and vaporized overhead comprising gases and distillatable hydrocarbons, with no substantial carryover of metals into the overhead;
• ii) condensing said overhead in at least one stage;
• iii) recovering at least part of said overhead as distillate;
• and
• iv) recovering said bottoms fraction containing organo-metallic compound decomposition products and wherein said bottoms fraction has no odor at room temperature and only a slight hydrocarbon odor at 400 F similar to hot asphalt and is essentially free of a strong burned odor.
