Abstract

Although investigations on upscaling methodologies across binder, Fine Aggregate Matrix (FAM), and Asphalt Concrete (AC) have been reported in the literature, additional evaluations should be performed considering the characteristics of the materials. This study investigates the relationship between the fatigue damage behavior of asphaltic material constituents based on a correlational assessment, as well as on experimental and analytical approaches. For that, rheological properties of asphalt binders were determined and AC and FAM were characterized by uniaxial tests. The fatigue parameters presented strong correlations across the scales and upscaling experimental equations were obtained from experimental data with good and promising results.
