The purpose of the field studies was to obtain information relative to the magnitude and the duration of the reduction in pavement supporting capacity due to frost action as measured by plate bearing tests, and to verify established criteria for the design and evaluation of pavements for airfields and highways. A test section was constructed at the Limestone Air Force Base, Limestone, Maine, with provisions made for performing plate bearing tests at selected locations to obtain comparative strength values at various periods during the year, and under varying ground water conditions. Additional areas were provided for excavation of test pits to measure density and water content variations, to study ice lens formation, and to perform California Bearing Ratio tests on the subgrade for the purpose of correlation with the other studies. Facilities were also provided for water table control and observation. Author
