Full-scale accelerated pavement testing (f-sAPT) is the controlled application of a wheel loading, at or above the appropriate legal load limit, to a pavement system to determine pavement response in a compressed time period. The acceleration of damage is achieved by means of increased repetitions, modified loading conditions, imposed climatic conditions (e.g., temperature and/or moisture), the use of thinner pavements with a decreased structural capacity, and thus shorter design lives or a combination of these factors. This synthesis study has the objective of expanding the foundation provided by NCHRP Syntheses 325and 235 on f-sAPT by adding information generated between the years 2000 and 2011 and identifying gaps in knowledge and future research needs. This synthesis is based on two major sources of information. A questionnaire was distributed to 43 known U.S. and international operators and owners of f-sAPT devices, the 50 U.S. state departments of transportation representatives, and a group of specialists active in the field of pavement engineering. The second source of information is the conference and journal papers published from 2000 to 2011. The author collected and synthesized the information and wrote the report. The members of the topic panel are acknowledged on the preceding page. This synthesis is an immediately useful document that records the practices that were acceptable within the limitations of the knowledge available at the time of its preparation. As progress in research and practice continues, new knowledge will be added to that now at hand.
