Abstract
In this study, the generalized Voigt model is employed to represent the dynamic behavior of asphalt mixtures. Parameter values of the rheological model were identified using a method based on a system identification approach. From the results of parameter identification using dynamic flexural test data, it was found that the frequency range that the model covers broadens with increasing the number of elements and that the eight elements model covers the range of 0.01 to 100Hz. The estimated parameters showed that the elastic moduli of the model are independent on temperature, while viscous moduli decrease with temperature rising.
