摘要: The healing phenomenon of asphalt mixtures has been postulated mainly due to the effect binder. A study binder’s alone without considering interaction aggregates can simplify problem at same time provide a clearer picture behavior binder, and finally be compared with mixture’s for improvement current pavement design methodology. This conducted an analysis fatigue using laboratory Dynamic Shear Rheometer (DSR) testing specifically designed intermittent loading sequence. Based on fundamental dissipated energy concept, ratio change (RDEC) approach which successfully applied in mixtures’ is adopted As results, presented performance both qualitative quantitative ways. It proved strong correlation between binder observed HMA mixtures. rate proposed evaluate potential binders used investigate type, stress/strain level, temperatures healing. also once more validated applicability advantages concept describing research finding will help select higher potential, damage resistance longer service life.
