Available in PDF, EPUB and Kindle. Book excerpt: Rammsonde profile measurements and surface strength (Clegg impact) tests were conducted at selected sites in Antarctica on the snow roadways between McMurdo Station and Williams Field as well as on the aircraft skiway. Rammsonde measurements were also made at several points on the South Pole Station and South Pole Stations. The purpose of the snow pit work was to investigate possible correlation between Rammsonde hardness data of the snowpack and the snow characterization data consisting of profiles of temperature, density, stratification, grain size, and metamorphic state. California bearing ratio (CBR) testing, to supplement previous work, was done in a laboratory coldroom at Michigan Technological University using snow that had been harvested near Houghton, Michigan, during the winter of 1985-86. A report on this will be published separately. The samples were prepared in a compaction machine and tested after sintering times of 7, 14 and 21 days at -10 C.A field test was conducted in Houghton with binder/additive-snow mixes in situ. Keywords: Aircraft skiways, Antarctica, Snow roads, Snow runways, Field tests. (SDW).

Available in PDF, EPUB and Kindle. Book excerpt: Dynamic tests were performed to determine the Young's modulus of sea ice, derived from longitudinal wave velocities measured with a soniscope. Static tests consisted of standard ring tensile strength and simple beam or flexural strength tests. The strength data were plotted on a base of the brine volume for each test. The test results indicate that the annual sea ice at McMurdo Sound is capable of supporting cargo type aircraft. Snow runways capable of supporting a C-130 aircraft on wheels and providing marginal support to a C-121 can be constructed either with the Peter plow or with the pulvimixer. However, the runway would be reliable only during comparatively low temperatures (

Book excerpt: Techniques and equipment have been developed to utilize clean, undisturbed snow as a building material for emergency and temporary roads, runways, and skiways in polar regions. However, these routes are often needed in areas where the snow is contaminated. During Deep Freeze 65, a compacted-snow runway was constructed in an area of contaminated snow near McMurdo, Antarctica. The area had been contaminated by oil spillage, soot, and debris from previous operations. Physical property tests were conducted on the compacted snow near the end of Deep Freeze 65 and during Deep Freeze 66. It was concluded that contaminated snow can be processed to produce load-carrying material capable of supporting C-130 aircraft and other heavy loads at temperatures below 20F; however, because of the extra work involved to clear and process such snow, its marginal load-carrying capabilities at temperatures above 20F, and the possibility of low-strength areas, its use is not recommended where clean snow is available. New processing techniques resulted in improved quality control of compacted snow, and it was recommended that effort be continued to improve processing techniques. (Author).
