Purpose: The purpose of the subsurface temperature investigations has been the determination of the temperature changes occurring in and beneath airfield pavements during winter weather conditions, and a correlation of this data with air temperature and cumulative, degree-days below freezing data obtained during the same period of time. Depths of freezing temperature penetration and data relative to heat movements through the surface and from deep earth have also been obtained. The scope of this report covers an investigation of subsurface temperatures occurring under various types of surfaces, including rigid and flexible type pavements, and typical regional turf conditions. The investigation includes the measurement of air temperatures throughout out the period of investigation, together with the determination, at various intervals throughout the winter season, of the temperatures existing at or near the surface of the pavement and at various depths below the pavement to depths varying from 7 to 8 feet. The report covers the data obtained from both thermocouple readings, obtained from thermocouples buried below the pavement surface, and glass bulb thermometers readings, used in wells inserted in the pavement to various depths. The period of testing covers, in general, the period from September 1944 to May 1945.
