Abstract: Personnel of the U.S. Army Engineer Research and Development Center (ERDC) were tasked by Headquarters, Air Combat Command, to evaluate the Department of Defense’s (DoD) minimum asphalt concrete thickness criteria outlined in Unified Facilities Criteria 3-260-02. Recent improvements to the DoD’s flexible pavement design procedure and a renewed emphasis on the design and construction of contingency pavements has prompted concerns regarding the design and evaluation of thin asphalt concrete pavements. An evaluation of the DoD’s minimum asphalt concrete thickness criteria was conducted during February 2007 to April 2008 under the ERDC’s Hangar 4 test facility. The project consisted of constructing a full-scale test section with six varying test items that represented three airfield types encountered in both peacetime and contingency scenarios. Four of the items met the DoD’s minimum asphalt concrete thickness criteria, and two items did not meet the criteria. Each item was instrumented and trafficked with either a C-17 wheel or an F-15E wheel using a Heavy Vehicle Simulator. Traffic test results concluded that the DoD’s current minimum asphalt concrete thickness criteria are acceptable. Further results from the evaluation are presented and include material characterization tests and data, rut depth measurements, centerline and cross section profiles, falling weight deflectometer data, instrumentation response data, and forensic investigation assessments.
