Characterisation of surfacing materials for orthotropic steel deck bridges. Part 2: numerical work
The lifespan of surfacing course materials like mastic asphalt on orthotropic steel deck bridges is quite short when compared with that of ordinary road pavements. Several problems including cracking and rutting of the surfacing materials have been reported in many countries. This is the second part of the two papers on characterisation of the behaviour of typical surface course materials for orthotropic steel deck bridges. In this paper, details of the constitutive model and its numerical implementation are presented. An important component of the model is an unconditionally stable, implicit Euler backward algorithm for the integration of the constitutive equations. Comparisons of model predictions and laboratory measurements at different temperatures, deformation rates and confining stresses are shown. Utilisation of the model in finite element analyses has enabled the investigation of the inelastic response of a 3D orthotropic steel deck bridge subjected to dual wheel loads.
