Concrete Evidence: A New Overlay for Orthotropic Decks

This article examines two bridge deck overlay replacement projects that have been under way in the Netherlands this summer. The projects represent the culmination of a major research effort into solving problems with fatigue damage to steel deck bridges. Projects to rehabilitate the Hagenstein bridges on the A27 and the Moerdijk Bridge on A18, which started this summer, are the first large scale applications of a new concrete overlay system that is intended to solve the problems with fatigue on such structures. The major research project that has been carried out over the last six years , including a pilot project in 2003, to try and develop a new high strength concrete wearing course for orthotropic steel bridges which can also extend the service life of the total construction by solving fatigue problems in specific deck details. The resulting solution is very promising since it turns the deck plate into a much more rigid construction with a higher 'plate factor' due to the monolithic composite interaction between the reinforced high performance concrete overlay and the steel deck plate.
