Predicting the deterioration rates of bridge elements is an important component of any bridge management system. This is because the prediction of future bridge funding needs is based in part on the existing and future conditions of the bridge element. A methodology for predicting the deterioration rates of bridge elements was developed on the basis of an analysis of historical data from bridge inspections. The methodology is applied to the bridge deck, superstructure, and substructure as example elements. General deterioration curves were developed for the three major bridge elements by material type. More detailed deterioration curves for the bridge elements were also developed for various subgroupings of these elements divided by material and environmental factors.
