Corrosion of metallic dowel bars is a significant issue that can lead to a decrease in the long-term performance of jointed plain concrete pavements. The high chloride exposure from deicing agents coupled with moisture penetration at transverse joints creates a corrosive environment. Corrosion development is a complex phenomenon affected by both pavement design and climatic features. Current pavement performance prediction models are unable to account for dowel corrosion due to the limited understanding of this. This project was performed to improve the existing pavement performance models by incorporating the effect of dowel corrosion in the model framework. A review of available corrosion databases and corrosion prediction models was performed to inform the development of a novel accelerated dowel corrosion laboratory investigation. A range of dowel bars currently on the market were evaluated to quantify the development of corrosion and the effect on pavement performance. The results from the accelerated corrosion study were used to update the existing faulting prediction framework to account for the effect of corrosion on faulting development. The faulting model was calibrated with field performance data from in-service concrete pavements. The products of this project can be used to better account for the effect of corrosion on long-term dowel performance. Additionally, the revised faulting model enables the consideration of non-metallic dowels and alternative dowel coatings, which are being implemented in many long-life paving projects.
