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.

Recovery of the bitumen and asphalt concrete properties with rejuvenator

Collected scientific works of Ukrainian State University of Railway Transport, 2021
The main factor in the decreasing in the quality of asphalt concrete with time is thehardening of the bituminous binder, which occurs under the influence of high environmentaltemperatures, moisture and oxygen. Considering this, one of the ways to extend the service life ofasphalt pavements isto implement procedures to prevent deterioration of the ...

Evaluating the Change Characteristics of the Microstructure of the Modified Plant Asphalt Using Soft Computing to Improve the Road Performance for Green Environment

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
Due to the diversity of plant asphalt sources and refining processes, the composition and properties of the various plant asphalts are also different. The plant asphalts are used to preserve the green environment. The natural material is eco‐friendly; hence, the usage of plant asphalts is getting promoted these days. There are some problems in the road

The compartmented alginate fibres optimisation for bitumen rejuvenator encapsulation

Journal of Traffic and Transportation Engineering (English Edition), 2017
This article presents development of a novel self-healing technology for asphalt pavements, where asphalt binder rejuvenator is encapsulated within the compartmented alginate fibres. The key objective of the study was to optimise the compartmented alginate fibre design, i.e., maximising amount of rejuvenator encapsulated within the fibre.

Rejuvenation of aged asphalt binder extracted from reclaimed asphalt pavement using waste vegetable and engine oils

Case Studies in Construction Materials, 2019
After many years in service, bituminous material in roads becomes aged and starts losing its properties. Aged bitumen becomes more brittle and causes a reduction in pavement strength with a decrease in the service life of pavement.
