Research on the Mechanism of Interaction between Styrene-Butadiene-Styrene (SBS) and Asphalt Based on Molecular Vibration Frequency
TL;DR: In this article, the effect of styrene-butadiene-styrene (SBS) polymer on the molecular vibration of each component of asphalt, the vibration spectrums and binding energy of the systems composed of SBS and each component molecule of asphalt were calculated.

A novel methodology for the evaluation of low temperature failure properties of asphalt binders
TL;DR: In this paper, the authors present the results of an experimental investigation that focused on the failure properties of asphalt binders at low temperatures, based on the use of the dynamic shear rheometer equipped with 4mm parallel plates.

Application of asphaltenes in high modulus asphalt concrete
TL;DR: In this article, the application of asphalt binders from different sources modified with asphaltenes in high modulus base courses (HMAC) was investigated, and it was determined that binders derived from the Alberta oilsands modified with AS can achieve the performance grade requirements for HMAC applications.

The colloidal structure of bitumen: Consequences on the rheology and on the mechanisms of bitumen modification
TL;DR: A general picture of bitumen structure is shown to emerge and it shows that a simple solvation parameter allows quantifying the effect of the asphaltenes on the rheological properties ofbitumen.

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.

New direct observations of asphalts and asphalt binders by scanning electron microscopy and atomic force microscopy
TL;DR: In this article, a network of asphaltene molecules with regard to asphalt gel was revealed by using atomic force microscopy (AFM) and SEM observations with very low resolution.
