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

Study on the Wetting and Permeation Properties of Bio-Oil as Bitumen Rejuvenator. [PDF]

Int J Mol Sci, 2023
In order to explore the diffusion and regeneration of bio-oil in aged bitumen, waste cooking oil (WCO), waste wood oil (WWO) and straw liquefied residue oil (SLRO) were selected in this paper. According to the surface wetting theory, the contact angle is obtained by combining laboratory experiments with molecular dynamics (MD) simulation, and the ...

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 ...

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 ...

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 ...
