Ice Roads
An ice road or ice bridge is a human-made structure that runs on a frozen water surface (a river, a lake or a sea water expanse).Masterson, D. and Løset, S., 2011, ISO 19906: Bearing capacity of ice and ice roads, Proceedings of the 21st International Conference on Port and Ocean Engineering under Arctic Conditions (POAC), Montreal, Canada.Proskin, S.A. and Fitzgerald, A., 2019, Using a limit states approach for ice road design, GeoSt.John's, St. John's.Spencer, P. and Wang, R., 2018, The design width of floating ice roads and effect of longitudinal cracks, Proceedings of the Arctic Technology Conference (ATC), Houston. Ice roads are typically part of a winter road, but they can also be simple stand-alone structures, connecting two shorelines.Michel, B., Drouin, M., Lefebvre, L.M., Rosenberg, P. and Murray, R., 1974, Ice bridges of the James Bay Project.

Ice Road Saimaa
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Popular Mechanics
''Popular Mechanics'' (sometimes PM or PopMech) is a magazine of popular science and technology, featuring automotive, home, outdoor, electronics, science, do-it-yourself, and technology topics. Military topics, aviation and transportation of all types, space, tools and gadgets are commonly featured. It was founded in 1902 by Henry Haven Windsor, who was the editor and—as owner of the Popular Mechanics Company—the publisher. For decades, the tagline of the monthly magazine was "Written so you can understand it." In 1958, PM was purchased by the Hearst Corporation, now Hearst Communications. In 2013, the US edition changed from twelve to ten issues per year, and in 2014 the tagline was changed to "How your world works." The magazine added a podcast in recent years, including regular features ''Most Useful Podcast Ever'' and ''How Your World Works''.

Ice Racing
Ice racing is a form of racing that uses cars, motorcycles, snowmobiles, all-terrain vehicles, or other motorized vehicles. Ice racing takes place on frozen lakes or rivers, or on groomed frozen lots. As cold weather is a requirement for natural ice, it is usually found at higher latitudes in Canada, the northern United States, and in northern Europe, although limited indoor events are held in warmer climates, typically on ice hockey rinks (motorcycles and ATVs only). Tracks in North America vary from 1/4 mile to several mile-long (~400 m to several kilometer-long) circuits. Track Tracks used for ice racing include ovals and road courses. Some tracks are dirt track racing tracks with the snow plowed off them. When there is no natural snow, an icy surface may be created by spraying the dirt surface with water when the temperature is below freezing. Artificial ice tracks (usually speed skating ovals) are used where it is not possible to construct natural ice tracks. Some track ...

Ice Pier
An ice pier or ice wharf is a man-made structure used to assist the unloading of ships in Antarctica. It is constructed by pumping seawater into a contained area and allowing the water to freeze. By repeating this procedure several times, additional layers are built up. The final structure is many metres in thickness, and strong enough to support container trucks. Operation Deep Freeze personnel constructed the first floating ice pier at Antarctica’s southernmost sea port at McMurdo Station in 1973."Unique ice pier provides harbor for ships," Antarctic Sun. January 8, 2006; McMurdo Station, Antarctica. Ice piers have been in use each season since, at McMurdo's natural [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Road
A snow road is a type of winter road, which is a road that is used or trafficable only in the winter.Adam 1978Abele 1990Proskin et al. 2011 Snow roads make up some or all of the on-land segments of a winter road. The snow is either compacted in place or, when there is not enough of it, is hauled from elsewhere, then compacted. The snow may be processed, for instance, by agitation to reduce the size of the particles before compaction.Lang et al 1997 Additional snow is also used to help protect the vegetation and as a means of improving trafficability. This snow, sometimes referred to as 'snow pavement', can be compacted to various level, depending on requirements and available equipment – a higher compaction will accommodate heavier vehicles and higher tire pressures.Russell-Head et al 1984 To increase the road's load capacity and its resistance to wear, water can be added onto the snow surface, resulting in a denser pavement and the formation of an ice cap. Ultimately, with a su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter Road
A winter road is a seasonal road only usable during the winter, i.e. it has to be re-built every year. This road typically runs over land and over frozen lakes, rivers, swamps, and sea ice.Proskin et al, 2011. Guidelines for the Construction and Operation of Winter Roads, Transportation Association of Canada.- IHSA, 2014. Best practices for building and working safely on ice covers in Ontario, Mississauga, Ontario, 43 p.- NorthWest Territories Transportation, 2015.

Tibbitt To Contwoyto Winter Road
Tibbitt to Contwoyto Winter Road is an annual ice road first built in 1982 to service mines and exploration activities in the Northwest Territories and Nunavut in Northern Canada. Between long, the road is said to be the world's longest heavy haul ice road and operates for eight to ten weeks starting in the last week of January. Most of the road (85%–87%) is built over frozen lakes, , with the remaining built on over 64 land portages between lakes. Construction and operation The winter road is constructed by Nuna Logistics and RTL-Robinson every January and takes about six weeks to complete. The first vehicle along each season is a Swedish-made Hägglund army-type reconnaissance vehicle designed to float if it falls through the ice; it tows an ice-thickness-detecting sonar. This is followed by road building equipment including "specialized low ground pressure equipment". The road, built extra wide to avoid blockages during blizzards and to allow opposing trucks to pass, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Ice Road

Ice Road Truckers
''Ice Road Truckers'' (commercially abbreviated ''IRT'') is a reality television series that premiered on History Channel, on June 17, 2007. It features the activities of drivers who operate trucks on seasonal routes crossing frozen lakes and rivers, in remote Arctic territories in Canada and Alaska. Seasons three to six also featured Alaska's improved but still remote Dalton Highway, which is mainly snow-covered solid ground. The newest seasons are mainly focused on Manitoba's winter roads. The series' 11th season finished airing on November 9, 2017. History In 2000, History aired a 46-minute episode titled "Ice Road Truckers" as part of the ''Suicide Missions'' (later ''Dangerous Missions'') series. Based on Edith Iglauer's book '' Denison's Ice Road'', the episode details the treacherous job of driving trucks over frozen lakes, also known as ice roads, in Canada's Northwest Territories. After 2000, reruns of the documentary were aired as an episode of the series ''Modern Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
