Abstract: Permafrost is rock, soil, or sediment that stays below 0 C for at least 2 consecutive years. About a quarter of the northern hemisphere's land mass is permafrost, and Alaska may be 85% permafrost. Permafrost is degrading. Uneven thaw is expected to significantly add to the current costs of road, pipeline, and airport maintenance over the next 20 years in Alaska. In the Arctic, permafrost degradation may impact training activities and increase operations and maintenance costs annually at U.S. Army installations. This work outlines a methodology to predict the probability that local infrastructure will incur damage (i.e., if a road will crack) based on the prob-ability that the infrastructure was built on a permafrost location.
