Bridge Element Deterioration of Concrete Substructures

This research project determines the average age of a concrete substructure element at transition from one condition state to the next. Because of necessary frequent repair, the state has accurate asset preservation models for elements such as bridge decks and steel coating to assist in bridge maintenance. However, no statistical or data driven model currently exists for predicting the deterioration of concrete bridge substructure elements.

This research develops a statistically driven model for deterioration of concrete columns. Specifically, Concrete Pile/Column (National Bridge/WSDOT Element 205) and Concrete Submerged Pile/Column (National Bridge/WSDOT Element 227) for both Eastern and Western Washington climates. The research demonstrates there is no significant deterioration difference between columns in Eastern and Western Washington. The research outcome is a Probability Transition Matrix and age of transition for dry and submerged concrete Pile/Column elements.
