Increasing the Lifespan and Resiliency of Bridge Superstructure Concrete Through Durability-Based Performance Evaluation

This research project, aligned with the National Center for Infrastructure Transformation's (NCIT's) focus on "Improving Durability and Extending the Life of Transportation Infrastructure," seeks to do a durability-based performance evaluation of the selected bridge deck concrete mixes and identify the deficiencies (if any) and areas of improvements for extending service life. The project aims to extend a previously developed durability evaluation Tool (TxDOT Tool) to predict four pivotal durability indicators [e.g., estimation of optimum SCM dosage for mitigating ASR, shrinkage-based cracking potential prediction, measuring formation factor-based transport properties (diffusion and sorptivity) followed by corrosion and F-T durability predictions] followed by service life evaluation under ambient field (temperature/RH), chloride, and freeze-thaw exposure conditions during the mix design stage for the selected deck mixes. Traditional ASTM/AASHTO tests will also be conducted to validate whether the Tool-based durability predictions are acceptable instead of conducting long-term laboratory testing. With parallel efforts, the performance of the selected bridges will be examined by analyzing the NDT-based condition assessment data along with consideration of the accelerated testing data (i.e., deck deterioration progression driven by live-load-induced damage) obtained by the BEAST and ADTT and environmental conditions data, leading to the development of adjusted models for predicting future performance and remaining service life. The remaining service life based on these adjusted field models will then be used to adjust the Tool-based material-level service life predictions, which is expected to improve service life predictions during the mix design stage leading to the benefits of extending bridge deck lifespan, optimizing investments, reducing disruptions, and ensuring safer commutes for the public.
