N2 - The purpose of this paper is to estimate the effect of asphalt content on dynamic characterization of hot-mix asphalt (HMA). For this objective, five varying asphalt contents were selected, mixtures with the same coarse aggregate gap gradation (CAGG). The dynamic modulus test method recommended by NCHRP 9-29 was adopted to evaluate the dynamic characterization of these materials. The dynamic modulus |E*|, phase angle and their master curve characteristic parameters were achieved to evaluate the performance of HMA. Finally, the rationality of the Hirsch prediction model to predict maximum value of dynamic modulus for this gradation is discussed. The results indicate that asphalt content has influences on viscous and elastic properties of mixture.
