Vacuum Residue as Antioxidant and Rejuvenator Agent for Bitumen

ES 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

NEWS 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.

Application of Waste Cooking Oil as a Rejuvenator for Aged Bitumen

IOP Conference Series: Earth and Environmental Science
Abstract Bitumen/asphalt is used as a binder in flexible pavements. It is obtained from petroleum which is a non-renewable source of energy. Therefore, use of recycled asphalt pavement (RAP) is sustainable and economical as it replaces the fresh bitumen in the mix design.

Recycling of waste oils as rejuvenators for aged bitumen in RAP

, 2022
The recycling of materials considered "waste" is an important goal for developing low environmental impact processes, even in pavement constructions. Therefore, the use of reclaimed asphalt pavement (RAP) is an important strategy in the preparation of new roads [1-2].

Effect of Bio-based Rejuvenators on the Properties of Rap Bitumen: a Review

International Journal For Multidisciplinary Research
Reclaimed asphalt pavement (RAP) contains aged bitumen that has become stiff and brittle after years of traffic loading and exposure to heat and oxygen. Using RAP in new pavement mixtures offers important economic and environmental benefits, but the hard aged bitumen in RAP reduces the flexibility and cracking resistance of the new pavement.
