The effect of skewing the transverse joints in concrete rigid pavements is studied through 3D finite element modelling. Models of multi-layered systems consisting of Portland cement concrete slabs, base and subgrade were developed. These consisted of slabs having straight as well as skewed joints. In order to study the state of stresses and strains in both straight and skewed slabs, the models were subjected to moving axle loads as well as non-linear temperature gradients. More refined models were developed and subjected to falling weight deflectometer dynamic loads to study the state of stresses at the dowels-concrete interfaces. The study, shows that skewing the joints did not reduce the level of stresses and strains in critical locations in the concrete slab. Also a close study of the induced stresses and strains showed that fatigue relations adapted for concrete pavements needed to be refined. The distribution of stresses around the dowel sockets indicates the formation of a tensile stress component, which initiates a tensile crack before any failure of concrete material in compression.
