Journal ArticleDOI
Identification of ageing state clusters of reclaimed asphalt binders using principal component analysis (PCA) and hierarchical cluster analysis (HCA) based on chemo-rheological parameters
Alexandros Margaritis,Hilde Soenen,Erik Fransen,Georgios Pipintakos,Geert Jacobs,Johan Blom,Wim Van den bergh +6 more
TL;DR: In this paper, chemical (SARA and FTIR ageing indexes) and rheological properties (master curve parameters, Glower-Rowe parameter and ΔΤc) of a large selection of Reclaimed Asphalt (RA) binders (19 samples) were determined to reveal their ageing level.
Journal ArticleDOI
On the Applicability of ATR-FTIR Microscopy to Evaluate the Blending between Neat Bitumen and Bituminous Coating of Reclaimed Asphalt
Alexandros Margaritis,Giorgio Tofani,Geert Jacobs,Johan Blom,Serge Tavernier,Cedric Vuye,Wim Van den bergh +6 more
TL;DR: In this paper, the applicability of Fourier transform infrared (FTIR) microscopy in attenuated total reflectance (ATR) mode to study the bituminous coating of Reclaimed Asphalt (RA) granulates is investigated.
Journal ArticleDOI
Influence of soft binder and rejuvenator on the mechanical and chemical properties of bituminous binders
TL;DR: In this paper, the authors compared the use of a softer binder and a rejuvenator and found that the rejuvenator results in similar rheological behaviour compared to the application of a soft binder.
Journal ArticleDOI
Investigation of Crack Propagation and Healing of Asphalt Concrete Using Digital Image Correlation
Navid Hasheminejad,Cedric Vuye,Alexandros Margaritis,Bart Ribbens,Geert Jacobs,Johan Blom,Wim Van den bergh,Joris J.J. Dirckx,Steve Vanlanduit +8 more
TL;DR: In this article, a digital image correlation (DIC) method is used to calculate the strain map on the surface of cylindrical asphalt specimens during the indirect tensile fatigue test.
Journal ArticleDOI
Physicochemical and Rheological Properties of a Transparent Asphalt Binder Modified with Nano-TiO2
Iran Rocha Segundo,Salmon Landi,Alexandros Margaritis,Georgios Pipintakos,Elisabete F. Freitas,Cedric Vuye,Johan Blom,Tom Tytgat,Siegfried Denys,Joaquim A. O. Carneiro +9 more
TL;DR: The transparent binders seem to be workable considering their viscosity, and exhibited values between the conventional binder and PMB with respect to rutting resistance, penetration, and softening point, and the addition of TiO2 seemed to reduce fatigue life, except for the 0.5% content.
