• Description:
  The goals of this research project were to develop, evaluate, and recommend changes necessary to integrate the AASHTO element-based inspection system into NYSDOT bridge management decision-making processes, guidelines, and bridge performance measures. The research developed a logic for identifying the work needs for each bridge based chiefly on AASHTO element inspection data. It also developed the logic for predicting the change in element condition states as a result of performing the needed work. The research developed and evaluated two alternative types of performance measurement concepts: (1) a bridge condition index, rated on a 0-100 scale, which is built upon a weighted average of condition state percentages of each element (2) a condition category assignment based on the estimated level of work needed on the bridge, where the work needed is determined by the selection logic developed as part of the research project. Finally, the research produced programming logic to implement the performance measurement and selection logic within the NYSDOT bridge database system.
