Summary: The frost investigation program, including studies at ten airfields, was authorized by the Chief, of Engineers by letter to the Division Engineer, New England Division dated 7 July 1944, subject : "Frost Investigation”. Frost investigation at five additional airfields in the Missouri River Division was authorized by the Chief of Engineers in 1st endorsement to letter dated 24 August 1944; from the Division Engineer, Missouri River Division, to the Chief of Engineers, subject: "Frost Investigation". The combined investigations included studies at 15 airfields with varying subsurface conditions located, in the northern part of the United States. The purpose of the investigation was to establish criteria and methods for the design of airfield pavements where conditions are conducive to frost action, both in theaters of operation and in the United States, and to establish criteria and methods for evaluation of airfield pavements where subgrade soils or base courses experience frost action. Extensive field and laboratory tests were, conducted together with theoretical and mathematical studies. At three of the airfields traffic tests with wheel loads ranging from 7,000 to-60,000 lbs. were conducted. The results of frost investigations made at Dow Field, Bangor, Maine, in 1943-1944, for the Pavement Evaluation Program, including results of traffic tests, have been utilized in this investigation. Based upon the studies performed, a method of design of flexible and rigid pavements over subgrades susceptible to frost act ion has. been included in the Ad Interim Engineering- Manual as Part XII, Chapter 4, entitled "Frost Conditions, Airfield Pavement Design". The design is applicable for evaluation of airfield pavements where subgrade soils or base courses experience frost action. NOTE: This file is large.
