Abstract:Bridges structures deteriorate over time due to various factors. Understanding the factors that affect bridge deterioration rates is necessary for state agencies to maintain the safety and functionality of bridges during their design service life. To improve deterioration modeling in Montana, significant factors affecting bridge deterioration were evaluated within the Montana Department of Transportation’s Bridge Management (BrM) software. The research improves existing deterioration curves established in Phase 1 of this research by considering different bridge groups, variables, NBI component-level data, and maintenance activities.
