Tyndall AFB Bomb Damage Repair Field Test, Documentation and Analysis
Abstract
The requirement for field testing of the existing Bomb Damage Repair (BDR) procedures under realistic field conditions, the testing of new BDR materials developed for AFWL and requirements for advanced research on debris backfills and equipment package optimization led to the AFWL/Tyndall AFB BDR Field Test. Five major tests and two smaller tests were run. Shortcomings of the AFM 93-2 repair process were identified, including the requirements for more realistic training, improvement in project coordination, improved methods of handling upheaved pavement and a more carefully designed AM-2 ramp attachment system. An optimum equipment package was designed using inventory equipment centered about a large rubber tired dozer. The need for heavier equipment was generally indicated by the field tests. Testing of debris backfill showed that compaction below the six foot level is not important for expedient repairs. Testing of regulated-set cement and PVC structural backfill modules was accomplished with unfavorable results. In general, structural backfill systems cannot compete with debris for expedient repairs. It was determined that development of regulated-set cement is not advanced enough to allow its inclusion in the USAF BDR program at this time. Crater data from 750 lb bombs in clay and sand from 25 lb C-4 charges were collected, and these indicated that the detonation in clay produced the worst repair conditions, although upheaval in the sand subgrade detonations was larger in relation to the crater volume.
