Summary

Complex modulus tests at four different confining pressures were conducted, and the stress dependence of the long-term equilibrium modulus was modeled using the Uzan model. The results show that the dynamic modulus increases and phase angle decreases with increasing confining pressures at relatively low reduced loading frequency, but the stress dependence is insignificant at high-reduced loading frequency. The Uzan model coefficient can be determined effectively by the proposed deviatoric stress master curves, and the relaxation spectrum of asphalt mixture can be modeled by a Gaussian function.
