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 (

Available in PDF, EPUB and Kindle. Book excerpt: This state-of-the-practice report on the design and development of roads and airfields is the eighth monograph in a series prepared by the Technical Council on Cold Regions Engineering of the American Society of Civil Engineers. Previous reports in the series covered such topics as frost action and its control embankment design, and arctic coastal processes. This book discusses such topics as: 1) Route-location/siting; 2) frost action; 3) design for permafrost conditions; 4) low temperature cracking; 5) maintenance; 6) use of geosynthetics; and 7) materials specifications and testing. This monograph contributes a substantial amount of new material to the Cold Regions Engineering series.

Download or read book Compacted snow Runways in Antarctica written by G. E. Sherwood and published by . This book was released on 1967 with total page 26 pages. Available in PDF, EPUB and Kindle. 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).
