Description
Summary:The report is based on an analysis of data obtained during the 1952-53 Snow Compaction Trials conducted at Kapuskasing, Canada. It is generally known that, if snow is intensively mixed before it is compacted, the hardness or bearing capacity usually continues to increase for some time after compaction. This process is commonly referred to as age hardening. At the present time the hardness of a snow cover as measured with a rammsonde is used as an index of its strength or trafficability. The ultimate hardness attained by the snow is determined by the type of compaction process used, the thermodynamic and mechanical properties of the snow, and the air temperatures. It is necessary to measure as many of these factors as possible in order to evaluate compaction processes. (Author)
