This report addresses issues related to optimization and standardization of current pavement management processes in Kentucky. Historical pavement management records were analyzed, which indicates that standardization is necessary in future pavement management decisions. Based on data patterns from Kentucky’s interstate and parkway systems, two distress threshold values and three stages of pavement distress development were defined in this research. Also, staged survival models were developed in this research to predict the duration of a pavement in each stage. These duration models can assist the agency in optimizing design strategies and conducting life-cycle cost analysis.
