Description: Technical Report
Summary: This report presents, in three volumes, a summary of the frost investigations which were conducted under the supervision of the Frost Effects Laboratory from 1943 through 1949 together with all data obtained from these investigations. Frost studies were first initiated at Dow Field, Bangor, Maine, in the winter and spring of 1944 to determine the influence of frost action in the subgrade soils beneath both rigid and flexible pavements upon the load carrying capacity of the pavements during the frost melting period. The need for such studies became apparent during the pavement evaluation program in 1943 when it became obvious that, during the spring thaws, evaluations of many airfields in the northern United States were controlled by conditions resulting from frost action in the subgrade soils. Since limited data were available at that time on the effects of frost action under airfield pavements, an extensive program of investigations were authorized by the Chief of Engineers for the purpose of developing and establishing design and evaluation criteria for such pavements. Frost investigations were conducted in the New England Division, the Missouri River Division, and the Great Lakes Division under the direction of the Frost Effects Laboratory, New England Division. The observations and testing of the effects of frost action were studied during the fiscal years 1943-1946 at 17 airfields located in the northern United States. Several laboratory studies were made on different phases of the frost-soil problem in addition to investigations conducted at various airfields to study the field effects. Theoretical studies to determine rates and depth of frost penetration were made. Thermal and physical constants necessary for mathematical analysis were obtained from tests performed under controlled temperature conditions to determine the thermal conductivity of frozen and unfrozen cohesionless materials. Work of previous investigators in this field was reviewed. A study was made of methods of making frost susceptible soils non-frost susceptible by the use of various admixtures and also of methods of preventing the leaching out of salt admixtures. The data in the Data Report were presented in 36 separate reports that were prepared during the various stages of the frost investigational program. NOTE: This file is large.
