ABSTRACT
Several large steel bridges in the Netherlands have been given an extended service life by the application of a thin layer of reinforced high strength concrete to the surface of the steel deck. This innovative renovation technique has been subject to ongoing development since 2000, and there is now a growing body of experience with regard to the design, construction and maintenance aspects associated with this product. The asset performance can be improved as a result of the application of this renovation method. The asset owner has a number of operational issues for steel bridges which suffer from fatigue damage in the orthotropic deck, and this renovation method can reduce the ongoing inspection and maintenance demands while extending the useful life of the bridge. Some of the experiences from a major renovation programme are presented, in terms of recent developments regarding the design, the specification, and the execution outcome.
