Assessing the impact of filler properties, moisture, and aging regarding fatigue resistance of asphalt mastic
Source abstract
Abstract
Asphalt mastic (bitumen + filler) plays an essential role in the fatigue performance of asphalt pavements. The time sweep test is one of the bestknown test methods for assessing fatigue performance, but fracture initiation in the specimen and the high stiffness of the mastic may bias results. These problems can be avoided with a hyperbolic specimen, but this test geometry is still largely unexplored. Therefore, 20 different asphalt mastic mixes were tested with the dynamic shear rheometer and hyperbolic specimen shape to identify the impact of various fillers and their properties, moisture, and aging on fatigue performance. These results were compared with the findings in the literature to investigate the applicability of this novel test method. Thus, a correlation could be derived between the fractional void and the fatigue performance of asphalt mastic. As also described in the literature, moist filler or water stored mastic reduce fatigue performance.
