Abstract : An extensive materials and equipment investigation was conducted in response to an U. S. Air Force requirement which specified the development of improved materials and methods to provide a rapid and permanent runway repair capability. Materials studies, tests, and evaluation covered both organic and inorganic materials. Both were found to meet the contract requirements, but an inorganic compound containing calcium sulfate hemihydrate, cement, TF-4 and water was selected as the most satisfactory end product. This material was selected on the basis of an impartial grading system. Both the organic and inorganic field tests included set time checks and load applications within 10 minutes to several hours after application of the mixture over various subsoil and fill materials, under specified environmental conditions. Paralleling materials testing, small-scale mixing and pumping machines were developed and built. Material set-up rates were adjusted to approximately 12 minutes. Slurry viscosity was reduced to the required pumping level by varying the TF-4 additive. The Fast-Fix formula and equipment will undergo further tests, including actual bomb crater repairs at Eglin Air Force Base, allowing Air Force technicians to operate the equipment. Details of these tests and further Fast-Fix improvement will be provided in Volume II of this report. (Author)
