STATE OF THE ART IN PREDICTING THE PROBABILISTIC RESPONSE OF PAVEMENT STRUCTURES

Current design procedures that assume a homogeneous material do not account for the limited pavement distress that is experienced in the field; rather they are based on a catastrophic occurrence of distress. Variability of stress due to load variables and variability of pavement strength due to material characteristics are related in several recent developments, generally by making gross transformations between a statistical confidence level and satisfactory performance. Reliability techniques are describe, and special attention is given to the Markov process. Reliability can be viewed as a probability that none of the following events occurs: (a) the number of overlays exceeds the allowed number/ (b) the total cost of maintenance and overlays converted to net present value exceeds the allowed cost; and (c) a user delay penalty cost exceeds an allowed value. /Author/
