Abstract:

This report presents a specification-type test method to characterize the impact of fine aggregate and material filler on the complex nature of fatigue behavior of asphalt mixtures. Dynamic mechanical tests using the dynamic mechanical analyzer (DMA) were performed for cylindrical sand asphalt samples made with pure binders, modified binders, and mastics to estimate viscoelastic characteristics and fatigue behavior. Test results were analyzed using viscoelastic theories and fatigue prediction models based on continuum damage mechanics. The mechanical effects of additives were investigated. In addition, researchers identified a reasonable definition of fatigue failure. This DMA protocol can also be used to investigate the impact of moisture on the cohesive strength and damage resistance of the matrix and/or the fine aggregate matrix.
