Previous research was conducted to determine if urethane foam would protect ice and snow surfaces from deterioration when subjected to summer season temperatures and solar radiation in the polar regions. The work proved the ability of urethane foam to provide thaw protection but disclosed two problem areas. These areas were trafficability and wind resistance. This report deals with these two areas as well as with transportation storage, foam generation, application, and maintenance associated with the task of providing a protective foam cover for ice and snow surfaces. The investigation of protective covers resulted in two final concepts which provide adequate resistance to traffic and wind are worthy of fullscale development. The two concepts are the regenerating foam-granulesnow cover technique, utilizing a layer of insulating granules covered by a flexible fiberglass laminate cover. Standard procedures for polar operations may be followed. Most of the equipment required for preparing and maintaining these protective covers is that normally used on polar runways. No major problems were found in the areas of transporttion, storage, generation and application of the protective foam. Author
