The influence of temperature, oxidation duration and air consumption on the operational properties of oxidized petroleum bitumens were determined. Samples of the obtained oxidized petroleum bitumen were analyzed with the determination of ductility (at 25 0C), penetration (at 25 0C) and softening point (ring-and-ball method).
