Abstract
Dowel bars in concrete pavements can effectively improve the performance of joints as well as the overall performance of pavements. This paper reviewed the mechanical behavior, structural numerical simulation analysis, testing study of doweled joints in concrete pavements, and the research work on the alternative dowel bars. The influences of dowel bar configuration, diameter, spacing, misalignment, rust, and the bonding between the surrounding concrete on the performance of doweled joints were also discussed in this paper. Limitations of theoretical research and test methods were mentioned after reviewing these aspects of dowel bars, indicating the direction for future research on doweled joints in concrete pavements.
