Abstract
The study estimated the damage of asphalt materials properties measured by modulus based on the fatigue damage as captured through fracture characteristics. Dynamic semi-circular bending (SCB) test was conducted on eighteen asphalt mixtures at three temperatures and a series of parameters were evaluated and further utilized to estimate the reduction coefficient (δSCB) related to the initial modulus. Finally, this study developed a nomograph to estimate δSCB with increasing crack length. Overall, this study established the correlation between reduction in the modulus and fracture properties of asphalt mixtures, and thus developed the conceptual outline to formulate a nomograph.
