MAINTENANCE STRATEGY FOR LARGE ADRIATIC BRIDGES

This paper presents the study to develop an effective maintenance strategy for large Adriatic Bridges. This unique group of bridges includes six large reinforced concrete arches exposed to aggressive maritime environment. Over the years many deficiencies and rapid degradation were identified on older bridges. The combinations of aggressive exposure conditions, poor detailing and construction errors resulted in serious deterioration of structural members, with reinforcement corrosion being a major issue. In addition to these, the importance of adequate and regular maintenance activities was completely overlooked. As a result, huge, complex and expensive repair works are needed. To eliminate the errors of the past and ensure smooth service and efficient management of large Adriatic Bridges in the future, an extensive project to develop an appropriate maintenance strategy was started recently addressing all relevant issues - structural performance monitoring, assessment procedure, suport in a decision-making process, reliability analysis etc.
