Vacuum Residue as Antioxidant and Rejuvenator Agent for Bitumen

open access: yesES Materials & Manufacturing
This research presents a laboratory study on a 100/130 bitumen treated with a vacuum residue (VR), i.e., the residue of vacuum distillation of oil, as a possible effective agent against bitumen aging. The VR was added to the bitumen before aging, in order to evaluate its antioxidant effect, and after aging to evaluate the rejuvenating effect.

NEW EXPERIMENTAL APPROACHES TO ANALYSE THE SUPRAMOLECULAR STRUCTURE OF REJUVENATED AGED BITUMENS

open access: yesNEWS of National Academy of Sciences of the Republic of Kazakhstan, 2019
Bitumen aging occurs through volatilization, oxidation and supramolecular assembly variations involving drastic changes in the structure of the material. Due to the ageing process of bitumen and its corresponding increase in viscosity, the stiffness of asphalt pavement is increased during its lifetime.
