Abstract: Assessment and analysis of existing road bridges is required for their continued use, due to
increase in traffic volume and weight, along with deterioration and ageing of the bridge
materials. Current codes for design of new bridges are not effectively applicable for this type
of the assessment, due to theirs conservative assumptions regarding load and resistance
modelling. Site-specific bridge assessment, based on measured Bridge Weigh-in-Motion (B-
WIM) data can reveal hidden bridge reserves in terms of load carrying capacity, leading to
reduction of maintenance costs and extension of remaining bridge service life. Two types of B-
WIM measurements (short and long term) will be investigated, along with multi-level
probabilistic assessment method where additional information is applied in every step to show
benefits of measured data. Bridge performance indicators based on B-WIM measurements will
be defined. Cost-benefit analysis will justify the contribution of this assessment approach in the
optimization of the bridge management system.
