The purpose of this report is to present the results of a condition survey performed at Minot Air Force Base (MAFB), North Dakota, during 11-15 April 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost action to the pavement facilities.
