Abstract :
A significant difference between essential and preventive maintenance is that essential maintenance is normally undertaken when the bridge reliability has fallen to or below the target value while preventive maintenance is undertaken when the bridge reliability is still above the target value. This paper aims to know and identify the main and minor defects in the bridge in Egypt in order to prepare corrective plan to solve these defects in preventive stage. A sample of bridges distributed overall Egypt and had different conditions will be chosen, studied and analyzed. The sample includes 45 bridge and its maintenance reports. The end result of this paper will be a general reliability –based framework to be used by General Authority for Roads Bridges and Transportation in Egypt in order to plan optimal strategies for the maintenance of its bridge network.
