Abstract: Traditional deicing approaches such as salting pollute the environment and corrode reinforcing steel bars in concrete. Meanwhile, recently emerging carbon nanofiber material has improved electrical conductivity, a large ...

Abstract: Roads and other infrastructure in Western Alaska are difficult to design and build owing to the high cost of construction materials and the ice-rich permafrost foundation. The present study explores methods to treat locally ...

Abstract: Two high-salinity soils with different types of salts were tested to assess the effects of freeze-thaw (F-T) cycles on their volumetric and low-temperature shear behavior. The testing program, including freeze-thaw cycling ...

Abstract: Deep ice lenses or excess ice in permafrost in Arctic oil fields on Alaska's North Slope, the Mackenzie Delta, or Eastern Siberia in Russia create challenging issues for oil well completion design. As thaw subsidence ...

Abstract: This paper presents an innovative fungal mycelium-based biofoam. Three different mixing protocols with various substrate materials, including wood pulp, millet grain, wheat bran, a natural fiber, and calcium sulfate, and ...

Abstract: Monitoring the soil freeze-thaw process is of great importance to engineering design of infrastructure, observation of hydrology, variation of climate, and existence of vegetation in cold regions. This paper presents ...

Abstract: In cold regions, snow and ice cause serious safety problems to the transportation system. South central Alaska, particularly Anchorage, is susceptible to a number of icing events resulting from frequent freeze/thaw cycles ...

Abstract: This paper presents the results of more than one year’s monitoring efforts and analysis of the effects of environmental variables on the dynamic properties of a selected bridge in Anchorage, Alaska. A seismic monitoring ...
