Abstract :
Through stress relaxation test at experimental condition of different temperature and different aging degree of asphalt mixture of AC-13C, Relaxation modulus master curve under reference temperature of asphalt mixture were fitted by different viscoelastic models, and the six-units generalized Maxwell model was recommend to characterize the aging asphalt mixture relaxation property. Then Parameters of the viscoelastic model of asphalt mixture at different aging degree was obtained by nonlinear regression, and the aging asphalt mixture relaxation property can be approached.
