• Abstract:
  The objective of this research project is to develop a durable repair system for deteriorated steel bridge piles that ; can be implemented without the need for dewatering. A rigorous survey of the relevant practice nationwide was ; conducted to inform and direct the remaining research efforts. The current state-of-practice was critically ; reviewed and the most promising alternatives were identified for detailed investigation. The structural ; performance, constructability, and economy of the existing systems were considered. A simplified but reliable ; framework for assessing the condition of deteriorated piles is proposed. The framework was used to direct the ; full-scale testing of artificially deteriorated and repaired piles. Accelerated environmental exposure tests were ; conducted to evaluate the durability of the different repair systems. The results of the full-scale tests and the ; environmental durability tests were used to inform a life-cycle cost analysis to identify the most economical ; repair systems based on initial costs, life-cycle costs, agency costs, and user costs. To evaluate the performance ; of the repair systems in ' real ' applications, a field installation was conducted. Based on the research findings, ; guidelines for the design, construction, and maintenance of the systems will be developed to facilitate transfer of ; the technology to TxDOT bridge maintenance operations.
