TRAFFICABILITY IN SNOW TRENCHES,
Abstract
During the 1960 Greenland test season, a study was made on the trafficability of snow-trench floors, including rail traffic on a natural snow floor and heavy wheel-load traffic on both natural snow and snow processed by a Peter snow miller. The effect of aluminum landing mats and a neoprene-coated nylon membrane was investigated. It was found that a natural-snow trench floor is not capable of supporting heavy, standard wheel-load traffic. The processed-snow floor is capable of supporting 7000-lb wheel loads for at least 500 coverages without any indications of failure or surface wearing. The use of landing mats appears to be unnecessary, and the membrane as a wearing surface is unsuitable because of its slippery surface. The natural snow floor is capable of supporting mine rail traffic and may be able to support a full-size railroad system, but further study is necessary. Investigation is also needed on heavy wheel-load traffic in a curved trench and at a higher speed. (Author)
