This paper demonstrates that by more realistically modelling the corrosion process, the service life of PT structures can be modelled more consistently with case studies where the service life goes well beyond the limits that chloride induced corrosion models indicate. This may contribute to environmental sustainability and economic efficiency in their management. Acknowledgements This work was developed within the activities founded by the FABRE Consortium.
