On Site Monitoring for Studying the Effects of Environmental Loads on the Corrosion Rate
Among the approximately 5,000 bridges which are maintained by the infrastructure operator ASFiNAG a total number of 1,500 objects are overpasses. Particularly their substructures are subject to increased chloride contamination due to the application of de-icing salt on the road. Sooner or later this results in damage to the infrastructure and, hence, in a reduced service life. This paper provides a critical discussion of data collected from an on-site monitoring and from weather stations. It reveals important interrelations and dependencies to the corrosion rate. The monitored time variant corrosion rate indicates a significant mathematical detectable periodicity. In particular, the paper focuses on the interactions between environmental loads and corrosion rates of the reinforcement of concrete columns. Finally a temperature compensated empirically model for prediction of the corrosion rate by using environmental and monitoring data will be proposed.
