Shakedown of Unbound Pavements

In this paper, the researchers seek to establish a mechanistic approach based on shakedown theory to predict various types of failure modes (including rut formation and subsurface slip) due to plastic and elastic deformation. To facilitate this approach, researchers establish a minimum shakedown load by varying the geometry of material failure mechanisms. This paper differentiates itself from a previous study using a mechanistic approach to shakedown by using two different collapse mechanisms. Researchers do conclude, despite the apparent efficacy in the application of shakedown to pavement analysis, that the model has limited use due to the perfect plasticity of the Mohr-Coulomb model and proposes to extend classical shakedown theory to a model that would accommodate the hysteretic behavior of soils under these load conditions
