Numerical Study of Damages in Bridge Surfacing Structures by Five-Point Bending Tests

Orthotropic steel deck bridges (OSDBs) are widely used in long-span or movable bridges around the world. In the Netherlands, the surfacing structure of OSDBs mostly consists of multiple material layers. Early or accumulated damages of multilayer surfacing systems is a complicated and yet not properly solved technical problem. A three dimensional elasto-visco-plastic model based on the generalized Burger's model was developed and implemented in CAPA-3D for simulating fatigue damages in asphaltic materials. The material model was calibrated and verified by five-point bending fatigue tests on beam specimens of multilayer bridge surfacing structures. The finite element model is capable of simulating accumulations and distributions of damages in asphalt surfacing structures, and could be utilized as an auxiliary method to evaluate and design surfacing systems for OSDBs.
