Abstract:In the mid‐1990s, the Arizona Department of Transportation (ADOT) initiated the Maintenance Cost
Effectiveness study (SPR 371) with the development of plans and an experiment design to evaluate the
effectiveness of a variety of asphalt pavement maintenance treatments. During 1999 and 2001, ADOT oversaw
the construction of hundreds of experimental sections throughout the state under the Phase I, Wearing Course
Experiment (nine treatments and 82 sections at three sites), and the Phase II, Preventive Maintenance
Experiment (24 treatments and 137 sections at four sites). Work continued in 2006 and 2007 under the
Evaluation of Maintenance Strategies study (SPR 628) for ADOT with a yearlong program of pavement
performance monitoring involving manual pavement distress surveys and automated skid, friction, and surface
texture measurements at all the experimental sites. The project culminated with a detailed analysis of key
pavement performance data to compare the performance of the individual treatments and determine their
overall effectiveness. This report documents the independent findings of both the Phase I and II experiments.
