This report presents the state of the practice about commonly used expansion joint systems in bridges. Specifically, it summarizes performance data for each system type and contains examples of selection criteria and design guidelines. The report will be of interest to bridge engineers and designers, and any agencies responsible for bridge operation and maintenance. Topics covered include a review of the current practice, expansion joint types and features, selection criteria and design guidelines, provisions to test joint seal watertightness, and lessons for maximizing the service life of joint systems. Information in support of this study came from the responses to a survey questionnaire from 34 states and 10 Canadian provinces. Questions addressed design procedures, use and experience, construction practices, maintenance and rehabilitation, and problems. Supplemental information relating to bridge deck selection and design criteria was provided by several states. Portions of the joint system guidelines of these states, which are considered important for purposes of comparison, are contained in the report.
