Publication year: 2010 Source: Cold Regions Science and Technology, In Press, Accepted Manuscript, Available online 24 November 2010 Margaret M., Darrow Thermal degradation of permafrost beneath embankments is an on-going problem in highway design. In recent years, engineers with the Alaska Department of Transportation and Public Facilities have used a commercially available, two-dimensional finite element model to determine the embankment’s effect on the thermal regime of the foundation soils; however, the modeling was done with historic air temperature data and input parameters derived from the literature, rather than site-specific data. Temperatures and soil properties were measured at two different research sites in Alaska to compare against model results.
