In this process, the impact of the history of deterioration on the reliability of a structure is disregarded which may lead to inappropriate conclusions. The Improved estimate of service life of a bridge deck may help decision makers enhance the intervention planning and optimize the bridge life cycle costs.

The cost of repairs of existing prestressed concrete I-beams has been reported to range from 35 to 69 % of the cost of a superstructure replacement and is expected to extend the service life of a structure, along with replacing the deck joint (Needham and Douglas 2000).Bridge beam ends are specifically prone to corrosion and premature deterioration, typically due to bridge deck joint leakage TRB s National Cooperative Highway Research Program (NCHRP) Web-Only Document 88: Service Life of Corrosion-Damaged Reinforced Concrete Bridge Superstructure Elements documents the data utilized in the development and validation of the service life model presented in NCHRP Report 558: Manual on Service Life of Corrosion-Damaged Reinforced Concrete Bridge Superstructure Elements.

For the The project developed a manual that provides step--step procedures for assessing the condition of corrosion-damaged bridge elements. The manual also includes procedures that can be used to estimate the expected remaining life of reinforced concrete bridge superstructure elements, and to determine the effects of maintenance and repair options on their service life.
