Physico-chemical analysis of five hard bitumens: Identification of chemical species and molecular organization before and after artificial aging
TLDR
In this article, a physico-chemical analysis of five different types of bitumens, both before and after aging, was performed to determine both the aging effect on chemical species and the chemical organization as a function of the type of bitumen sample.About:

Investigation of the possibility of using waste cooking oil as a rejuvenating agent for aged bitumen
TL;DR: Using 3-4% of WCO the aged bitumen group 40/50 was rejuvenated to a condition that closely resembled the physical, rheological properties of the original bitumen, however, there was a difference in the tendency to ageing between the WCO rejuvenated bitumen and the virgin bitumen during mixing, transport and laying on the road.

Physical, chemical and rheological properties of waste edible vegetable oil rejuvenated asphalt binders
TL;DR: In this paper, the effect of waste edible vegetable oil on the rejuvenation of aged asphalt binders was investigated in terms of physical, chemical and rheological properties, and it was shown that waste vegetable oil can effectively soften aged asphalt.

Ageing in modified bitumen using FTIR spectroscopy
TL;DR: In this article, three modified binders (elastomer, plastomer and crumb rubber) and the base bitumen were subjected to different ageing conditions and the evolution of the chemical functionalities during ageing were tracked using FTIR spectroscopy.
Journal ArticleDOI
Molecular dynamics investigation of interfacial adhesion between oxidised bitumen and mineral surfaces
TL;DR: In this paper, the interfacial adhesion between oxidised bitumen and mineral surfaces at dry and wet conditions was investigated using molecular dynamics simulations using bitumen models and four representative mineral substrates (namely quartz, calcite, albite and microcline).

Effect of ageing on bitumen chemistry and rheology
Xiaohu Lu,Ulf Isacsson +1 more
TL;DR: In this article, the effect of ageing on bitumen chemistry and rheology was studied, where seven bitumens were aged according to the thin film oven test and the rolling thin-film oven test (RTFOT) and the binders were characterised using infrared spectroscopy, chromatography and dynamic mechanical analysis.

Comparison by Fourier transform infrared (FTIR) spectroscopy of different ageing techniques: application to road bitumens
TL;DR: In this paper, the authors compared a direct and continued methodological approach of bitumen oxidation process (adapted IR cell), a road ageing, along with two ageing conventional tests: the Rolling Thin Film Oven Test (RTFOT) and the Pressure Ageing Vessel (PAV).
