SEM Analysis on Fracture and Healing of Sand‐Asphalt ...

During a rest period, relaxation and chemical healing occur simultaneously in an asphalt concrete layer. Understanding the mechanism of healing is important in order to predict the fatigue life of asphalt concrete pavements. A replication technique for scanning electron microscopy is employed to study the process of fracture healing of sand‐asphalt mixtures. Three binders are investigated ...

20/09/2020  Subsequently, self-healing capability of asphalt mixtures was evaluated under the action of different healing time (i.e., rest period), healing temperature and fracture cycles. The healing performance of the asphalt mixture beams was evaluated by conducting three-point bending test. Additionally, the mechanism of the effect of different water compositions environments on the self-healing ...

FATIGUE AND HEALING CHARACTERIZATION OF ASPHALT MIXTURES

FATIGUE AND HEALING CHARACTERIZATION OF ASPHALT MIXTURES. This paper investigates the effect of the processes on fatigue fracture and fracture healing during controlled-strain, dynamic mechanical analysis (DMA) testing. Sand asphalt samples were fabricated with 2 SHRP-classified binders: AAD-1 and AAM-1. DMA testing was performed at 25C and 10 Hz.

01/01/2002  However, it is also true that thermodynamic changes in the surface energy are required to heal a fracture between the surfaces of the asphalt and the aggregate or within the mastic. The methodology and testing protocol for measuring the surface energy of asphalt are presented. Both the surface energy of dewetting (fracture) and the surface energy of wetting (healing) can be obtained
