Abstract
The feasibility of preconditioning deep snow, by elementary means, for improved trafficability, was assessed through laboratory and field experimentation. Preconditioning consisted of snow surface disaggregation and compaction with and without mixing additives, to a fraction of total snow depth, and ageing for a period of days at moderate freezing temperatures (0 to -20C). The firm snow platform thus formed is able to support bearing pressures and repetetive loads representative of the Iltis, 5/4 ton truck and M113 APC.
