In order to study dynamic mechanical properties of asphalt mix under two-point bend load, and the impact of load level to dynamic modulus, trapezoid beam method is employed to conduct dynamic modulus tests on asphalt mix SAC13 (Stone Asphalt Concrete with nominal maximum aggregate size 13 mm). Impacts of temperature, frequency and asphalt material on dynamic modulus and phase angle are analysed: dynamic modulus decreases as temperature increases or frequency decreases, while phase angle increases as temperature increases or frequency decreases. SBS polymer modifier can improve mechanical prope...
