Abstract: The Virginia Department of Transportation is deeply committed to the development and implementation of an efficient, cost-effective maintenance management system for its bridges. Much effort is being applied towards the development of a management system that will ensure that appropriate maintenance takes place at the optimum times. Within such systems, the ability to anticipate with reasonable accuracy how rapidly and in what fashion bridges will deteriorate is essential in optimizing expenditures of limited maintenance funds. The research described in this report was undertaken to provide this predictive capability. Specifically, the objective was to use existing bridge inspection data in conjunction with multiple regression analyses to develop models relating the rate of deterioration of structural components with variables such as age, loadings, and environmental factors and to evaluate the relative importance of these variables. In addition, these efforts include a discussion of current bridge management activities and recommendations on needed modifications to the VDOT record-keeping system.
