Abstract:

This report describes the development of bridge element deterioration rates using the NYSDOT bridge inspection database using Markov chains and Weibull-based approaches. It is observed that Weibull-based approach is more reliable for developing bridge deterioration curves. Both Markov chains and Weibull-based approaches have been incorporated into a computer program that generates deterioration curves for specific bridge elements, based on historical NYSDOT bridge inspection data going back to 1981. A computer program has been developed to generate deterioration curves and equations for bridge elements in New York State.
