| Abstract: | On basis of the Burgers model, a new model consisting of modified dashpot and Van Der Poel model was derived from rheological
and viscoelastic theory. Subsequently, triaxial repeated load permanent deformation tests of AC16 asphalt mixtures were conducted
to validate this new developed model. Parameters of new developed model were obtained by a nonlinear regression analysis of
test data, and then permanent strains and flow number of each mixture were calculated. The experimental results prove that
the new developed model can well describe three phases permanent deformation of asphalt mixture under repeated load and it
can be used for pavement mechanical analysis and rutting prediction. |
