Researchers surveyed state agencies and analyzed research on remaining service life measures in pavement and bridge management. After evaluating MnDOT's practices, investigators recommended a percent remaining service interval (PRSI) measure that could be adapted for uniform condition assessments of bridges and pavements. Further research would be required to identify PRSI factors and values for types of bridges and pavement, as well as to define and calculate other metrics recommended for asset sustainability and funding opportunity costs.
