Abstract: Abstract: In 2004, legacy ADR systems were found to be inadequate for supporting runway operations of large military aircraft. The inability to effectively operate both fighter and heavy cargo aircraft on the same repaired runway after an attack poses significant operational challenges. The U.S. Air Force Air Combat Command began the Airfield Damage Repair (ADR) Modernization Program to develop technologies to address operational limitations of current ADR equipment, materials, and tactics. The objective of the program was to modernize the Air Force’s ADR capability through development of new solutions suitable for both fighter and cargo aircraft and scalable to the threat or damage. Scalable ADR solutions improve minimum operating strip (MOS) decision making options. Technical solutions were successfully demonstrated as a part of the Critical Runway AssessmenT and Repair (CRATR) Joint Capabilities Technology Demonstration (JCTD) Program. One of the solutions successfully demonstrated was use of rapid-setting flowable fill backfill. This report describes testing of rapid-setting flowable fill material as a surface capping material for expedient crater repairs at the Silver Flag Exercise Site on Tyndall Air Force Base, Florida. Repairs were capped with rapid-setting flowable fill over varying types and thicknesses of backfill layers. Smaller-sized repairs were loaded with a load cart simulating F-15 aircraft traffic, while larger repairs were trafficked with simulated C-17 traffic. All repairs withstood more than 500 simulated aircraft passes before reaching failure.
