ABSTRACT:
Paraffinic fluxing components, e.g., paraffinic base stocks such as neutral oils or foots oil, can be added to asphalt composition and the resulting blend oxidized, e.g., by blowing, to improve low temperature properties at low addition rates (e.g., oil 1-5 wt. %). The resulting asphalt compositions exhibit important improvements in low temperature properties, resistance to thermal cracking and expanded useful temperature range.
