ANSWERS ON A FAST TRACK: ACCELERATED PAVEMENT TESTING IN THE UNITED STATES

Accelerated pavement testing is intended to address one of the fundamental problems facing the pavement community: evaluating and predicting pavement performance. As an alternative to the real-time approach, the accelerated pavement testing process increases the load conditions (frequency, magnitude, or both) so that the expected design traffic of 10 to 40 years duration can be applied to pavement test sections in weeks or months. The trend is to use mechanical systems to cost-effectively apply accelerated loading to test pavements. This article presents a brief overview of the status of accelerated pavement testing throughout the world and the direction it is taking in the United States, pointing out the benefits of this research technology to pavement design and rehabilitation. An insert with this article describes a National Cooperative Highway Research Program Synthesis of Highway Practice, "Application of Full-Scale Accelerated Pavement Testing", that is being prepared to provide detailed information on this subject as part of NCHRP Project 20-5, Topic 26-07.
