This paper presents an overview of the application of accelerated pavement testing (APT) to the evaluation of thin overlays over cracked asphalt pavement. The paper presents the approach used to develop the test plan and its implementation to date (the testing is not yet completed). Conclusions are drawn regarding identification of failure criteria and design of the experiment to match APT results to pavement management system (PMS) results. Instrumentation is discussed. The need for forensic trenching after APT to identify distress mechanisms in individual layers is also discussed. An approach to relate cracking densities on short APT pavement sections to cracking measures on full-scale pavement as used in PMS condition surveys is also discussed.
