| Description: | Technical Report Summary: The current concept of snow formation is presented by Ukichiro Nakaya to provide better understanding of snow dynamics involved in snow compaction. Conditions necessary for the formation and precipitation of snow are presented. The metamorphism of snow including firnification and hardening are discussed. Snow is considered as an engineering material with changeable mechanical properties easily modified by natural and artificial processes. Snow compaction techniques used in maintenance of roads and airport runways consist of cementing the first 3 or 4 in. of snow to the ground by rolling, thus forming a firm foundation for future surfaces. The equipment used in compressive snow compaction is described and the processes involved are studied. Compaction of deep snow beds by depth processing through scarification are discussed. Methods of snow road construction developed by the logging industry are appended. NOTE: This file is very large. Allow the browser several minutes to download the file. |
