The purpose of this synthesis is to gather information on the practices used by bridge owners to repair and maintain post-tensioned bridges. The goal is to facilitate knowledge transfer across state departments of transportation (DOTs), aiding bridge owners in the identification of repair practices that are working and that will extend the useful life of the bridges. The study captures the current practice used by bridge owners to repair and maintain post-tensioned bridges. It presents a literature review and results of a survey distributed to 50 state DOTs. Forty-five completed responses were received from the 50 state DOT survey sample, a response rate of 90%. Case examples of five DOTs’ post-tensioned bridge repairs and related maintenance actions are included; these present in-depth analysis of the methods and applications, challenges, and lessons learned of each action.
