| There are several major practical consequences of stress-dependent properties of unbound pavement foundations. Among those are the stress-dependent modulus and Poisson's ratio's that may change, the compressive stresses that are generated in materials under load, the stiffening and strengthening effect of repeated loading to progressively increase the unbound pavement materials resistance to permanent deformation. In order to study these, the algorithm for predicting deformations on conventional flexible pavements are proposed and the stress-dependent effects on layer deformation are presented in this paper by the developed stress-dependent finite element analysis program with the selected models. |
