Hence, in this case, bridge condition can be detected only by discrete inspections through bridge lifetime. Based on these inspections, different maintenance actions, ranging from doing-nothing to system-replacement, can by assigned. Combining inspection policy with age of maintenance and degradation process, taken from previous experience and available database of similar structures, can be used as an effective process in decision making among different maintenance actions. The aim of this study was to develop a statistical-oriented method of managing and predicting maintenance actions and choosing the suitable inspection time interval at different bridge ages based on distributions of the time of maintenance obtained from the past experience and available database.]]>Faber, M.,200012186194Godart, B. and P.R.
