ABSTRACT:
Methods and systems for efficiently manufacturing modified asphalt materials include agitating a base asphalt at a high shear rate using an in-line mixer equipped with a rotor-stator mixing tool while simultaneously exposing the asphalt to oxygen by blowing an oxygen-containing gas at a high gas flow rate through openings in the rotor-stator mixing tool and heating the asphalt at an elevated temperature.
