A Review on Bitumen Rejuvenation: Mechanisms, Materials, Methods and Perspectives [PDF]
Applied Sciences, 2019 This review aims to explore the state of the knowledge and the state-of-the-art regarding bitumen rejuvenation. In particular, attention was paid to clear things up about the rejuvenator mechanism of action. Frequently, the terms rejuvenator and flux oil, or oil (i.e., softening agent) are used as if they were synonymous.

Effects of Waste Cooking Oil on the Antiageing Ability of Bitumen
Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023 Ageing is considered one of the significant issues faced by bituminous mixtures. The short‐term ageing phase involves a significant rise in the bitumen’s viscosity, which may lead to early raveling and cracking. Antiageing additives are prescribed to reduce the effects of short‐term ageing.
