The traditional crater repair equipment and materials developed under the Rapid Airfield Damage Recovery (RADR) program, while highly capable, are large, expensive, and logistically challenging. Research projects from 2016 and 2017 identified lighter and leaner crater repair equipment and backfill materials in an attempt to decrease some of the economic and logistical burdens on the U.S. Air Force. The RADR Technology Integration Experiment assessed the lighter and leaner equipment, materials, and methods for small crater repairs in a relative full-scale environment. The experiment was conducted in August 2017 at the Silver Flag Exercise Site located at Tyndall Air Force Base, FL. The lighter and leaner technologies were compared with the traditional crater repair process. Flowable fill, polyurethane foam, cement-stabilized soil, and geocells with granular fill were proven to be viable backfill options for repairing craters when capped with rapid-setting concrete. This effort resulted in successful crater repair solutions using the lighter and leaner technologies with limited increases in repair time. An optimized small crater repair package was developed based on the results of this experiment. |
