Study on the microscopic characteristics and rheological properties of thermal-oxidative aged and virgin-old recycled asphalts
Yue Qin,Yongjun Meng,Yongjun Meng,Jiechao Lei,Tao Fu,Ruiguang Xu,Xiaolong Yang,Qixiong Zhao,Chenchen Xi +8 more
TL;DR: In this article, the authors investigated the thermal-oxidative aging and virgin-old recycling behavior of SBS polymer modified asphalt and found that the asphalt viscosity-temperature properties were more sensitive to molecular changes than fatigue properties.
Journal ArticleDOI
Effect of colloidal instability on the rheological and fatigue properties of asphalt binders
TL;DR: In this paper, the authors identify possible relationships between the chemical composition and the rheological and fatigue properties of asphalt binders and demonstrate that higher levels of instability are associated with a more viscous and stiffer response regardless of the type of considered original binder.

Blending efficiency improvement and energy investigation of recycled asphalt mixture involved warm mix technology
TL;DR: In this paper, Fourier Transform Infrared Spectroscopy was used to evaluate the blending degree of virgin and aged asphalts involved warm mix additive, and some factors such as blending time, blending temperature, and RAP content on the blending efficiency were investigated in the study.
Journal ArticleDOI
Impact of constituent migration on colloid structure and rheological characteristics of emulsified asphalt with self-crosslinking modifiers
TL;DR: In this paper, waterborne acrylate and polyurethane were investigated to further enhance properties of emulsified asphalt, as a novel modifier, and the change of chemical constituent during the emulsion-additives interaction was firstly characterized by gel permeation chromatography (GPC) test.

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.
