Description: Technical Report
Summary: A snow runway was built on deep snow on the Greenland Ice Cap and tested during the summer of 1955. The strip was constructed by members of the 1st Engineer Arctic Task Force using modified pulvimixers with heat. Testing included Rammsonde measurements, and snow temperature observations on the strip; undisturbed cores were taken and tested for density, structure, unconfined compressive strength, unconfined shear strength, and stress/strain relations. Large-scale testing was done with a Bros rubber-tired roller, and C-47, C-54 and C-124 type aircraft. A formulation between the ram hardness values and the unconfined compressive strength is developed, and the Rammsonde is suggested as a simple instrument for determining the bearing capacity of a snow. Formulas are given for the increase in strength of snow with decreasing temperature and also for the amount of age-hardening with time.
