—While in the design of flexible pavement the
significance of asphalt layers is understood, the role of granular
layers supporting the asphalt layers should not be
underestimated. The behavior of granular layers used in base,
sub-base or subgrade layer of flexible pavement is complicated
due to nonlinear elastoplastic response of materials subjected to
dynamic load of traffic. Shakedown theory integrated with
Mohr-Coulomb criterion is applied to simulate the response of
granular layers to dynamic loading in a numerical analysis. The
results of analysis is then compared to simple the results of
modeling without considering shakedown effects and the
conclusion is drawn.

numerical simulation, shakedown.
