The objective of this study is to develop a mechanical design method for doweled joint. In order to investigate the mechanical behavior of dowel bar, a mechanical model for dowel bar in transverse joint of concrete pavement based on three dimensional finite element method PAVE3D was developed. In the model, a dowel bar is divided into two segments embedded in concrete and a segment between them and these segments are modeled by the solution of the beam on elastic foundation and the three dimensional beam element, respectively. The model was verified by comparing the predicted strains in concrete slab and dowel bar with the experimental data which were obtained from loading tests conducted on a model pavement and an actual pavement. The effects of transverse joint structure and subbase stiffness on the stresses in dowel bar and concrete slab were investigated based on numerical simulations with PAVE3D.
