In-service performance of road concrete bridges – set up of case studies for novel pro-active maintenance methodology

Condition assessment of six bridges: Maslenica Bridge, Šibenik Bridge, Adriatic Bridge, Bridge of Youth, Homeland Bridge and Žeinci Bridge are presented in the paper. The bridges are of different type, age, material and traffic demands, but their in-service performance confirms steel corrosion in concrete as main deterioration cause. Influences of age, environment, climate and construction quality on bridge durability are analysed. The presented bridges will be used as case studies for proposed novel methodology of pro-active bridge maintenance based on visual inspection complemented with the non-destructive testing and application of numerical model for service life prediction.
