Effect of component characteristics on mechanical properties of asphalt: A molecular dynamics study
TL;DR: In this paper , the effects of component characteristics on the micromechanical properties of three common asphalts (AAA-1, AAM-1 and AAK-1) collected in the Strategic Highway Research Program's Materials Reference Library were studied by using molecular dynamics simulation methods.

Establishment of correlation model between compositions and dynamic viscoelastic properties of asphalt binder based on machine learning
TL;DR: In this paper , the authors used principal component analysis (PCA) and distance correlation coefficient (DCC) methods to determine the input parameters of the model, while three machine learning algorithms, i.e., SVM, relevance vector machine (RVM) and random forest (RF), were used to predict the dynamic viscoelastic properties of asphalt binders.

TL;DR: In this article , the degradation behavior of a 4.8 mm thick elastomeric bituminous geomembrane (BGM) immersed in pH 0.5, 9.5 and 11.5 synthetic mining solutions is examined over 26 months at 22, 40, 55 and 70°C.

Influence of the Instrumental Inertia Effect on the Asphalt Binder Oscillation Measurement
TL;DR: In this paper , the authors investigated the instrumental inertia effect in the asphalt binder oscillation test for a wide temperature range (40°C-140°C). And they found that inertia effects also happen to asphalt binders, especially for non-EMA.

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.
