Abstract: The dynamic moduli at various temperatures and loading frequencies were measured for each asphalt mixture used in an asphalt pavement with flexible bases, and the dynamic modulus master curves and time-temperature shift factors were determined according to the time-temperature superposition principle. The effects of temperature and frequency on asphalt mixture properties were studied using measured pavement temperatures and well-accepted frequency prediction method. Pavement response were calculated using dynamic moduli, and the results were compared with those obtained using the method in China specification. The analysis based on dynamic modulus is more reasonable since it can take into account the effects of temperature and loading frequency.
