MAINTAINING SAFETY AND SERVICEABILITY OF CONCRETE BRIDGES IN CROATIA

The paper discusses management, maintenance and repair of Croatian bridges. Unfortunately, activities related to bridge maintenance are not carried out regularly, but on the “ as-needed” basis with inspection and testing undertaken only when structural damage becomes self-evident. Poor in-service performance and condition of existing bridges in Croatia, led to the conclusion that currently employed approach to solving bridge maintenance issues is not satisfactory, and should be improved. The framework for more efficient bridge management in terms of bridge management system HRMOS exists. Unfortunately introduction of HRMOS did not ensure that the activities related to bridge maintenance are carried out regularly nor according to the prescribed procedures. To illustrate the grave consequences of neglecting the bridge maintenance activities, several case studies are discussed, including world-renowned structures such as Krk bridges. These clearly show that if we choose to act only when damage of a bridge structure becomes self evident, the repairs are not only expensive but very difficult to perform.
