FIELD TESTS OF RAPID REPAIR METHODS FOR BOMB-DAMAGED RUNWAYS (ABRIDGMENT)

Rapid repair of bomb-damaged runways is of vital concern to the U.S. Air Force. The results of field tests conducted under the direction of the Air Force Engineering and Services Center at Tyndall Air Force Base are presented. These tests were of various rapid rapair techniques that use methyl methacrylate (MMA) polymer concrete. This includes both user-formulated and commercially available MMA polymer concrete. Both spalls and craters were repaired. Full-depth polymer-concrete (PC) repairs, at-grade precast units, and precast units with PC caps are reported. The repairs were trafficked with both F-4 (27,000-lb single wheel) and C-141 (144,000-lb dual-tandem wheel) load carts. All of the crater repairs performed satisfactorily as did most of the spall repairs, which demonstrated the feasibility of using PC methods for the rapid repair of bomb-damaged runways.
