dc.description.abstractWheel trafficability tests on a snow trench floor were conducted at Camp Century, Greenland, in 1962, with 2 types of low-pressure tires and with standard truck tires on an M-54 5-ton truck with a 5-ton load. Skid tests were performed and the friction coefficient between the tires and the processed snow surface was determined. A 1300 ft long, standard gage railroad track was installed in the trench after the whe.el traffic tests. A standard size flatcar with a 30-ton load, towed by a 5-ton truck equipped with rail wheels, was used for rail traffic tests. It was found that the natural, unprocessed snow surface in a trench 26 ft below the snow surface is not suitable for extensive traffic with vehicles such as 5-ton trucks even when equipped with low-pressure flotation tires. However, a Peter plow-processed, age-hardened snow surface is capable of supporting a virtually unlimited amount of vehicle traffic using standard tires. Even heavier wheeled vehicles could be supported by a processed-snow trench floor. The friction coefficient was found to be in the range of 0.2 to 0.3. For transporting extremely heavy items, the use of a railroad system installed on an unprocessed snow trench floor is feasible but expensive. The installation of a railroad system in a covered snow trench presents no serious problems.en_US
