Experiences in the Performance of Bridge Bearings and Expansion Joints Used for Highway Bridges

Domestic Scan 17-03, Experiences in the Performance of Bridge Bearings and Expansion Joints Used for Highway Bridges, was conducted March 21 through 25, 2018. It was initiated to facilitate the exchange of recent ideas and best practices for bridge bearings and expansion joints and included design, performance evaluation, and maintenance and repair/reconstruction. Discussions involved staff from design, construction, maintenance, and operations of state and other transportation agencies. Details (i.e., materials, span arrangements, and geometry) for various bridge types and sizes were examined. Lessons were drawn from both the good and bad experiences by the various participating agencies. The team selected scan hosts that would encompass a wide range of service conditions for bearings and joints. Considerations included such items as: climate challenges of the regions in which they are located, traffic volume, and project size. General topics of interest to the scan team included: Design and details, construction specifications and maintenance procedures for durable bearings and expansion joints that have a history of good in-service performance; Visual inspection and other testing of joint and bearing details; Specialized technology and standards used in monitoring, inspection, and repair of joint and bearing details, with the goal of ensuring safety and serviceability, minimizing downtime during bridge construction and rehabilitation; Relative costs for design, construction, maintenance, and inspection of various joint and bearing details; and Lessons learned and suggestions for improvement.
