Influence of the Skid Resistance of Ultrathin Wearing Course with Various Types of Asphalt Binders

Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020
Ultrathin wearing course (UTWC) has been widely applied in both asphalt pavements preventive maintenance and functional overlay. This study’s objective is to evaluate the influence of different modified asphalt binders with warm mix additives on the skid resistance of UTWC and to reveal the attenuation law of skid resistance of UTWC.

Evaluating the Fatigue Resistance of the Innovative Modified‐Reinforced Composite Asphalt Mixture

Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020
Fatigue failure is regarded as one of the most common failures in the road pavement and necessitates spending huge cost annually to maintain the road. Asphalt binder modification and asphalt mixture reinforcement are among the commonly used methods to increase the pavement resistance to a failure caused by fatigue.

Evaluation of the Physical Performance and Working Mechanism of Asphalt Containing a Surfactant Warm Mix Additive

Advances in Materials Science and Engineering, Volume 2020, Issue 1, 2020., 2020
This paper analyzes the influence of a surfactant warm mix additive on unmodified asphalt’s conventional performance, viscosity‐temperature characteristics, surface energy, and spreading performance on aggregate surfaces. The effect of the additive on asphalt’s microstructure was explored by infrared (IR) spectral analysis.
