Since corner breaks are one of the major structural distresses in jointed concrete pavements, this research study focuses on the determination of the critical bending stresses at the corner of the slab due to the individual and combination effects of wheel loading and thermal curling. A well-known slab-on-grade finite element program(ILLI-SLAB) was used for the analysis. Based on the principles of dimensional analysis, the dominating mechanistic variables were carefully identified and verified. The resulting corner stresses were compared to theoretical Westergaard solutions. Adjustment factors were introduced to account for this discrepancy. Prediction models were developed as an alternative to the very time- consuming and complicated F.E. analysis to estimate stresses for design purposes with sufficient accuracy.
