Abstract : 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 (ACC) began the Airfield Damage Repair (ADR) Modernization Program to develop technologies to address operational limitations of current ADR equipment, material, and tactics. The objective of the program was to modernize the Air Force s ADR capability through development of new ADR solutions that are suitable for both fighter and cargo aircraft while scalable to the threat or damage. These solutions were successfully demonstrated as a part of the Critical Runway AssessmenT and Repair (CRATR) Joint Capabilities Technology Demonstration (JCTD) Program for small (8.5 ft by 8.5 ft) crater repairs. This report describes the use of new ADR technologies for repairing large (30 ft by 30 ft) craters at the Silver Flag Exercise Site in Tyndall Air Force Base, Florida. Modernized ADR technologies were successfully demonstrated in a series of three different large crater repairs. Two repairs utilized flowable fill backfill, while one used a crushed stone backfill. The repairs conducted using flowable fill backfill withstood 1,500 simulated C-17 aircraft passes before reaching failure, while the repair backfilled with crushed stone failed at 400 passes.
