| Abstract: | Through quoting viscoelastic theory, Burgers model is used to simulate viscoelastic behavior of asphalt mixture, and the effect of overload, braking force and longitudinal slope on pavement structure is analyzed by finite element method. At last, general law of shear stress on surface course on is obtained which provides reference for pavement design. |
