The report presents the results of a study to determine the relationship between the Freezing Indexes computed using mean air temperature and those computed using pavement surface temperature. The study is based on subsurface temperature data available at the Frost Effects Laboratory consisting of periodic subsurface temperature readings throughout a complete normal freezing period from three airfields and limited readings from a fourth airfield, all located in the northern part of the United States. From these readings a factor for modifying the Air Freezing Index is obtained and applied to the theoretical equations, and a correlation made between the observed depth and predicted depth of frost penetration.
