Sažetak
To extend service life of the Krk Bridge, as one of the most important infrastructure reinforced concrete objects in Croatia, in the sub-structure of the large arch, an active cathodic protection system is installed. Paper describes basic working principles of cathodic protection systems and shows phases of system installation, results of system efficiency monitoring and result analysis. It is shown that, for successful interpretation of measuring parameters, and for efficiency of cathodic protection system assessment, application of statistical methods is necessary. Implementation of this procedure into our practice is of great importance, because we considered that cathodic protection (CP) may be required for service life extension for other Adriatic arch bridges, such as Pag and Šibenik bridge.
