Abstract : The purpose of this research is to develop techniques for rapidly repair-ing bomb damaged runways. Structural concepts for filling and/or spanning the crater are studied. Spanning systems, such as clear span and intermediate support systems, structural fill systems including inter- locking fills, and waterbag systems are considered as possible solutions. Only one concept, a honeycomb structural fill technique, fulfills the requirements of simplicity, speed, and dependability to merit further testing. This technique consists of filling a large portion of the crater with several modules constructed of interconnected, vertically placed polyvinyl chloride (PVC) pipes. Laboratory tests are conducted on bonding agents, capacity of individual pipe, several different size modules, and various module arrangements. The F-111 aircraft wheel loads are considered as the design loading. Results of these tests lead to a PVC module design for full-sclae field tests. A small preliminary field test indicates that the repair technique is feasible. (Author-PL)
