Accelerated pavement testing (APT) has predominantly been used for understanding pavement behavior for design and rehabilitation of pavements, with less emphasis on maintenance and pavement preservation applications. This has primarily been driven by need, and partly by the assumption that APT is not suited to maintenance and pavement preservation treatments due to the low test speeds. However, with road authorities in much of the world spending considerably more on maintenance and pavement preservation than new construction, the use of APT has been explored as a means of providing rapid comparison and evaluation results that can aid in the selection of optimal treatments. The purpose of the Transportation Research Board's (TRB’s) 86th Annual Meeting Session 594 (presented in 2007) was to present and discuss experience where APT has been successfully used for the assessment of pavement preservation and maintenance strategies. This introduction to Transportation Research E-Circular E-C139 highlights some of the information shared at the session with regard to the use of APT to evaluate maintenance and pavement preservation treatments. This information was gathered from the papers presented, a discussion held after the presentations between the panel of presenters and the audience, and additional comments from an ad hoc critical review of the papers and this summary by members and friends of TRB’s Full-Scale and Accelerated Pavement Testing Committee. It is intended that these ideas be used to motivate and better plan future APT research for evaluation of maintenance and pavement preservation treatments, and improve the quality and usefulness of results from APT in this area.
