This paper establishes a finite element method (FEM) model to predict rutting development of a double-layered pavement system with stone mastic asphalt as its upper layer and mastic asphalt as its bottom layer, which is widely used in orthotropic steel bridge paving. In addition, it presents the influence of pavement thickness and overloading on rutting occurring in the pavement of an orthotropic steel bridge. The results show that the MA layer contributes to an overwhelming majority of permanent deformation; furthermore, within a certain range, rutting depth increases rapidly with the rise of pavement thickness. Finally, a circular road tracking test was conducted to verify the FEM prediction. The comparison between test results and FEM results shows that the model is accurate. The results of this study can be used as reference for the design of pavement on steel decks.
