N2 - Lightweight orthotropic steel bridge decks have been widely utilized since the 1950s. In the last three decades, severe problems were reported in relation to asphaltic surfacing materials on orthotropic steel deck bridges. The research aims at developing an FE tool to simulate and understand the performance of asphaltic surfacing structure, so as to improve the design of surfacings and increase service life. In this investigation, an analysis of two extreme cases of composite beam models is first presented to provide a conceptual understanding of composite actions. The specialized material models for asphaltic layers and interface layers developed at Delft University of Technology with the numerical platform CAPA-3D are followed. Results of FE simulations for three different fixed-load positions are presented. Last, simulations of the bridge subjected to a moving load are introduced. The distribution of strains and the temperature influence of the Merwede bridge are discussed.
