Abstract : This report is concerned with the evaluation of a variety of potential approaches to the rapid repair of bomb-damaged runways, the development of these materials systems, and a small-scale field demonstration of their utility. Fifteen distinct approaches were evaluated in the laboratory: a graded density urethane foam, sulfur, chemical grout, liquid plug, thermosetting resins, prepreg fiber reinforced sheets, Joosten process solidification, asphalts, calcium acrylate, calcium-ligno sulfonate, fuel oil-molasses, quick-set cements, epoxy with expanded fillers, and resin/cement systems. The systems which best filled the requirement of time of set, ease of application, and structures, were the following: epoxy/sand, quick-set cement/epoxy, and quick-set cement/sand. Small-scale field trials of these systems indicated that one or more of them could be tailored to meet test requirements, but that considerable R and D work was yet necessary to prove their full utility. Recommendations for a further R and D program are given. (Author)
