Abstract: This work has been possible due to collaboration between the Ministère des Transports du Québec and the Centre de Recherche sur les Infrastructures en Béton de Université Laval at the restructuration of Dufferin-Montmorency overpass. The demolition of structures that haven’t reached their total service life time allowed the production of a great quantity of information on a prestressed structure of the Quebecer road network. In chapter 5, observations on prestressed structures have been grouped. This kind of information is, most of time, unavailable on an existing structure due to impossible inspection. In chapter 7, a classification of different exposure conditions of the inspected structural elements is showed as well as a numerical technique for predicting the time before corrosion starts. The last two chapters relate discussions on the actual state of this structure which is particular because one section has never been exposed to traffic.
