Abstract:

It is the intent of this paper to demonstrate how purely probabilistic arguments can be used to formulate a rational (phenomenonological) model of the particulate media that comprise pavement systems. It is demonstrated that for a special case the resulting mathematical equations for vertical stress distribution generated by the deterministic and probabilistic approaches are very similar. However, the major distinction between the two models is that the probabilistic model for vertical stress depends on parameters and the concept of the distribution of stress at a point.
