In this study, the effects of nano‐cobalt oxide (nano‐CoO) (1 and 2% by asphalt binder weight) on the rheological behavior of the asphalt binder and mechanical characteristics of asphalt mixtures were examined. To evaluate the behavior of the asphalt binder at moderate and high temperatures, the dynamic shear rheometer (DSR) test was used.

Adhesion of Nano‐ZnO Modified Asphalt and Its Influence on Moisture‐Sensitive Properties of Mixtures
This study investigates the effect of nano‐ZnO on modified asphalt’s adhesion characteristics by preparing various mixtures with 0%, 1%, 2%, and 3% nano‐ZnO contents. Within the study context, the adhesion characteristics of asphalt mixtures with different nano‐ZnO to limestone, basalt, and granite contents are studied using a boiling test. The surface‐

Self-Healing Effect of Various Capsule-Core Materials on Asphalt Materials
To further investigate the self-healing mechanism of microcapsules and exclude the interference of capsule-wall materials, a bi-plate test and a molecular model of asphalt and capsule-core materials were established using dynamic shear rheometer (DSR ...

Physical and Rheological Properties of Asphalt Binder Modified with Recycled Fibers
The price of asphalt binder has increased dramatically due to the increase in oil prices and the increase in traffic volumes occurring worldwide. This situation has prompted calls for greater viscosity, lower‐cost asphalt for pavement construction, and the development of alternative materials that have a good rheological effect, are less expensive, and

Laboratory Investigation of Using Calcium Lignosulfonate as an Oxidation Inhibitor in Bitumen
Asphalt mixtures are the major constituent of road constructions. Those mixtures expose to high‐temperature levels during the construction process and their life cycle. The bitumen aging occurred because of the harmful effects of elevated temperatures upon the asphalt mixtures, which leads to oxidation, evaporation, and physical hardening within the ...
