Microstructural modifications in bitumens rejuvenated by oil from pyrolysis of waste tires. [PDF]

Front Chem
IntroductionBitumen is the viscoelastic fluid binding the crushed stones and mineral aggregates in the asphalt material used to pave roads around the world. During the paving procedure, the volatile compounds are lost and oxidization occurs with variation of the mechanical characteristics (aging); thus, the material becomes rigid and brittle over time ...

Influence of rejuvenators on bitumen ageing in hot recycled asphalt mixtures

Journal of Traffic and Transportation Engineering (English ed. Online), 2018
The use of reclaimed asphalt pavement (RAP) in new hot mix asphalt (HMA) by means of hot recycling techniques generates the advantage linked to the exploitation of both lytic and bituminous component, consequently leading to the decrease of both virgin ...

Conductive Compartmented Capsules Encapsulating a Bitumen Rejuvenator [PDF]

Processes, 2021
This paper explores the potential use of conductive alginate capsules encapsulating a bitumen rejuvenator as a new extrinsic self-healing asphalt method. The capsules combine two existing self-healing asphalt technologies: (1) rejuvenator encapsulation and (2) induction heating to create a self-healing system that will provide rapid and effective ...

Unraveling the critical indicators for evaluating the high-temperature performance of rejuvenator-aged bitumen blends

Case Studies in Construction Materials, 2023
This study aims to systematically investigate the influence of rejuvenator type/dosage and the aging degree of bitumen on the rutting resistance, flow behavior, and elastic/creep potential of rejuvenated bitumen at high temperatures.

Bio-Oils as Asphalt Bitumen Rejuvenators

MAIREINFRA 2023, 2023
Bitumen rejuvenators are used to improve or restore the physical and mechanical performance of aged bitumen. Traditional bitumen rejuvenators are a product of crude oil. As crude oil production declines and the environmental and financial costs of crude oil increase, there is an urgent need to identify more environmentally sustainable bitumen ...

Aging and rejuvenation effects on the rheological response and chemical parameters of bitumen

Journal of Materials Research and Technology, 2023
The rejuvenation efficiency of aged bitumen is the main concern when developing rejuvenating agents. It is necessary to develop a method to assess the efficiency of rejuvenators using rheological parameters in the whole frequency region. To this end, the

The role of rejuvenators in embedded damage healing for asphalt pavement

Materials & Design, 2021
Rejuvenator encapsulation technique showed great potential for extrinsic asphalt pavement damage healing. Once the capsules are embedded within asphalt pavement, the healing is activated on-demand via progressing microcrack.
