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.

Investigating the healing capacity of asphalt mixtures ...

20/11/2020  When the iron slag content was 2%, the healing ratio of the asphalt mixture reaches the maximum value, and its fracture strength after healing could be recovered to more than half the initial strength. However, when the iron slag content was further increased to 4%, the healing ratio of the mixture was lower than at 2%, which indicates that the iron slag additive plays a limited role in ...
