Beschreibung
Zusammenfassung:	An asphalt mixture comprising an oligoterpene composition and reclaimed asphalt and/or virgin asphalt, a method of preparing said asphalt mixture, a bituminous binder-oligoterpene blend and a method for rejuvenating reclaimed asphalt or treating virgin asphalt are disclosed, wherein the oligoterpene composition comprises at least one oligoterpene with at least two isoprene moieties selected from a diterpene, a triterpene, a tetraterpene, a pentaterpene and a hexaterpene. The method of preparing an asphalt mixture comprises mixing the oligoterpene composition with reclaimed asphalt and/or virgin asphalt. The oligoterpene-bituminous binder blend, comprises 0.5-50 wt. % of the oligoterpene composition based on the total weight of the blend. The method for rejuvenating reclaimed asphalt or treating virgin asphalt comprises mixing the oligoterpene composition with reclaimed asphalt or virgin asphalt to form a modified asphalt.
