A laboratory study was conducted to determine if binder elasticity tests of asphalt binders could be used as an indicator of the fatigue characteristics of Hot Mix Asphalt (HMA) mixtures. This concept was evaluated by comparing the ranking of several binders' elasticity test results to the ranking of the corresponding mixture fatigue cracking characteristics. Binder elasticity was measured using the elastic recovery and multiple stress creep recovery test (MSCRT) tests, whereas the mixture fatigue was measured using overlay test based fatigue approach and two linear viscoelastic continuum damage (VECD) analysis methods. Overall, the rankings determined from the binder and mixture analyses indicated that no definitive trend between binder elasticity and mixture fatigue rankings could be established.
