An alternative method of prioritization for concrete bridge maintenance, repair, and rehabilitation activities is required due to the inability of the current system to manage the increasing numnber of aging concrete bridges. The Concrete Bridge Prioritization System was proposed because of its ability to address the critical technical parameters of safety and cost benefit in prioritization of funding and work allocation. The analysis includes four parts, service life assessment, service life extension, cost calculation, and prioritization. The system combines these parts to optimize consideration of the technical parameters. A systems engineering approach to the investigation and design of the Concrete Bridge Prioritization System is included.
