Finding the link between visual inspection and key performance indicators for road bridges

Based on the rating from visual inspection and proposed weighting through component, system and network level, assessment procedure resulting with set of six most important Key Performance Indicators (KPI) for road bridges is presented. Those are: bridge condition assessment, structural safety, traffic safety, durability indicator, availability and bridge importance in the network. KPIs organised in the radar shaped diagram serve for priority repair ranking decisions. The procedure is elaborated at the sample of five actual bridges: two reinforced concrete arch bridges, one with solid and other with hollowed cross- sections ; one frame type bridge with V shaped piers ; one precast slab overpass ; one solid slab continuous bridge with Y type piers. Bridges are built between 1958 and 2001 and are located either at the state or at the local roads in Croatia. Spans are varying from 9.5 to 72 m and overall lengths from 22 to 120 m.
