This study examines pavement management models using data from the Oklahoma DOT. Using 16 years of data collected with the Deighton Total Infrastructure Management System (dTIMS), the current models for predicting pavement deterioration are examined, compared, and, if necessary, recalibrated using the real-world data. The study contains a spreadsheet-based tool for managing pavement which could be of interest to anyone looking to either implement a similar tool, or justify the expense of detailed pavement monitoring data.
