Abstract: Mineral lubricant base oils (e.g., neutral oils) can be added to asphalt composition to improve low temperature properties at low addition rates (e.g., oil 1-5%). Rerefined oils (boiling above about 177.degree. C. (350.degree. F.)) have the same properties as virgin mineral lubricant base oils, but most rerefmed oils are too dark in color to be used as lube oil base stocks. Their use in asphalt would be ideal as color is not a problem and they are much cheaper in cost than virgin base oils. This can permit disposing of rerefined motor oil. The resulting asphalt compositions exhibit important improvements in low temperature properties, resistance to thermal cracking and expanded useful temperature range.
