INTERACTIVE PAVEMENT BEHAVIOR MODELING: A CLUE TO THE DISTRESS-PERFORMANCE-PROBLEM

A framework and suggested methodology for identifying objective relationships between pavement distress and performance is presented. The nature of the problem and the suitability of two widely used models of pavement performance are reviewed. The status of pavement behavior modeling is assessed, and a more comprehensive theory is advanced based on the hypothesis that (a) the levels of different types of pavement distress behavior are interdependent through time and (b) pavement behavior elements are recursive in that they depend on their own historical values. The viability of the theory is investigated through postulating a deterioration mechanism for flexible AASHO Road Test sections. A preliminary interactive model involving three behavior subsystems (rutting, cracking, and roughness) is described. (Author)
