Assessment of reinforcement corrosion and concrete damage on bridges using non-destructive testing

Abstract

Management of bridges in Croatia and their vulnerability to reinforcement corrosion is discussed in the paper. New maintenance approach, where visual inspections are combined with the non-destructive testing methods, is proposed and demonstrated on six representative bridges. Using this methodology, reinforcement corrosion on structural elements may be detected earlier and more precisely. Obtained results as well as correlations between different measured parameters are important input parameters for prediction of future degradation of structures and decision making for future maintenance activity.
