Summary and Assessment of Arizona Department of Transportation’s Maintenance Cost-Effectiveness Study

In 1995, Arizona Department of Transportation (ADOT) initiated research project SPR 371, Maintenance Cost Effectiveness Study. That project identified the maintenance surface treatment alternatives suitable for evaluation by ADOT, developed a consensus on which alternatives to test, evaluated the performance and cost effectiveness of those treatments, and identified procurement issues that inhibit effective pavement maintenance. Between 1999 and 2002 over 200 bituminous test sections were constructed at different locations throughout Arizona to evaluate the performance of different types of bituminous surfaces, including wearing courses (Phase I), surface treatments (Phase II), and sealer-rejuvenators (Phase III). This paper summarizes the current status of ADOT’s Maintenance Cost Effectiveness Phase I and II test sites, including a discussion of the original intent of ADOT’s test sections and the available data. This report also includes recommendations for moving forward or closing the two study phases.
