Abstract:

The Washington State Department of Transportation (WSDOT) has taken steps to improve the quality and durability of modular bridge expansion joints that have a movement rating greater than 150 mm. Expansion joints are subject to a greater number of load cycles than normal bridge components. As a result of premature fatigue failures of modular bridge expansion joints in Washington State and elsewhere, WSDOT requires that all modular joint components meet fatigue design and testing requirements. Components are designed for a fatigue life of 100 million cycles. Fatigue design and testing requirements are included in the contract specifications. Improved specifications and quality control during manufacture and construction are needed in order to eliminate possible loss of quality caused by competitive bidding and bid shopping. Preapproved expansion joint models and manufacturers should be identified in the contract plans and specifications. Contractors should identify which manufacturer is selected at the time of bid submission. It is recommended that modular bridge expansion joints have at least a 5-year guarantee on performance and durability.
