TL;DR: In this paper, the effects of SBS type and dosage, asphalt type, processing technology and environment on phase structure and separation are reviewed and the correlation between SBS modified asphalt and chemical composition, micromechanics, rheological properties, and other aspects are analyzed.

TL;DR: In this article, the authors evaluated the performance of asphalt mixture exposed to dynamic water and chlorine salt erosion, the asphalt mixture dynamic water-salt erosion apparatus was self-designed and the test parameters were reasonably set for the accelerated simulation of chlorine salt-water-temperature-load coupling action to asphalt mixture under real working conditions.

TL;DR: In this article, the effect of phosphorus slag powder (PSP) and polyester fiber (PF) on the rheological properties of asphalt binder and performance characteristics of resultant mixtures was investigated.

TL;DR: In this article, the swelling principle of desulfurized rubber asphalt (DRA) was examined and the performance of DRA fabricated with various rubber powder contents under different shear conditions and development time.

TL;DR: The results illustrate that the prepared SAP water-retaining asphalt mixture has good potential in reducing dust and enhancing road performance and may help to understand the influence of SAP on water retention performance and decipher its underlying mechanism.
