Effect　of　furfural　extract　oil　(FEO)　on　performance　of　asphalt　and　comparison　between　mixed　asphalt　blended　with　FEO　and　pure　asphalt　were　investigated.　Results　indicate　FEO　could　be　used　as　modifier　of　hard　asphalt　to　prepare　a　higher　penetration　grade　asphalt　whose　properties　can　satisfy　technical　requirements.　However,　compared　with　pure　asphalt,　mixed　asphalt　exhibits　lower　ductility　value,　less　ability　to　resist　rutting　at　high　temperature　and　cracking　at　low　temperature,　and　poorer　anti-aging　performance.　Therefore,　mixed　asphalt　should　be　cautiously　used　in　areas　with　harsh　environment,　and　the　performance　of　mixed　asphalt　should　be　fully　evaluated　by　comprehensive　analysis　if　the　mixed　asphalt　has　to　be　used.
