Abstract : Existing profilometers, each developed for highway applications, have limitations in respect to profiling bomb damage repaired airfield pavements. The components of existing profilometer systems are discussed in relation to the general requirements of a profilometer for bomb damage repaired pavements, as are each of the profilometers themselves. The conclusions drawn concerning the use of existing profilometer systems for bomb damaged airfield pavements are that they process profile data to provide information appropriate to highway operations; they do not function effectively at slow speeds, which may be necessary on an extensively damaged runway; and the costs prohibit supplying a unit to each station which may require expedient repair. Crater upheaval is the disturbance about the crater itself, which may not be detectable by the human eye. The string line method, presently used by the Air Force to detect crater upheaval, is difficult to perform and sometimes unreliable. Other possible methods are introduced and should be integrated into a test plan to determine the worthiness of each of crater upheaval detection. Keywords: Airfield pavement, Bomb damage, Crater upheaval, Profilometer, Rapid runway repair.
