Abstract : Although processing and compacting increase the density and bearing capacity of snow for use as roads and trails, these processes have not been able to achieve the degree of densification that occurs naturally as snow slowly metamorphoses to glacier ice. A literature review and preliminary laboratory study showed that additional experiments are needed to determine the load distribution in a snow pavement and to determine the optimum snow temperature range at which processing and compaction are most effective. In addition, statistical and engineering analyses of the physical properties of natural and processed snow should be conducted using available field data in order to define the stress distribution within a snow pavement.
