The Kentucky Transportation Cabinet (KYTC) initiated the study KYSPR 17-532, “Deterioration Modelling of Bridges on BrM 5.2.3,” so it could receive assistance identifying and employing bridge deterioration and cost forecast modeling for its bridge maintenance program. The Kentucky Transportation Center (KTC) was to help coordinate KYTC in adapting BrM 5.2.3’s deterioration and cost modelling features and update the existing guide material to reflect all changes for BrM 5.2.3. This study included acquiring access and becoming familiar with AASHTO Bridge Management (BrM 5.2.3) software. It was also to explore opportunities for any training on BrM and BrM 5.2.3’s deterioration and cost modeling capabilities and adapt them to best meet KYTC’s maintenance needs for four National Bridge Elements (NBE) — Reinforced Concrete Deck (12), Steel Open Girder/Beam (107), Strip Seal Expansion Joint (300), and Moveable Bearing (311). But the lack sufficient and reliable data for element-level deterioration modelling has proved a hindrance and impeded the completion of the research. As data points are collected, deterioration rates should be checked occasionally to see if they require calibration.
