The finite element scheme of viscoelastic structural dynamics with fractional derivative three elements model constitutive relation was derived based on the analysis of the theory of the fractional derivative three elements model in this paper. And the numerical solution of the finite element equation was calculated using the numerical algorithm for the dynamics equation of the fractional derivative viscoelasticity structure. Moreover, the efficiency of the finite element scheme was confirmed by the dynamic viscoelastic response of two-dimensional asphalt pavement.
