The objective of this thesis is to develop a tool to predict the behavior of flexible pavements vis-a-vis the rutting phenomenon. Through a literature review, we have come to modify the model according to the validation of the time–temperature superposition principle. The application of this principle leads to a simplification of the methodology for characterizing asphalt mixtures by reducing the minimum number of test from 9 to 6. Work methodology centered around the ESSO model allow the development of a predictive tool, the OPECC© tool (Outil de Prédiction de l’Évolution du Comportement de la Chaussée). This tool allows the user to predict the behavior of a pavement structure vis-a-vis rutting and fatigue cracking while integrating different modules that change the mix properties depending on temperature and stress frequency, and as a function of traffic patterns and road structure. This tool, through various simulations and fine-tuned according to measured results on existing roadways, proves its potential to highlight the differences attributed to various stress and design conditions which are part of roadway dimensioning.
