Engineering Applications in Permafrost Areas 577 Design and performance of the Inuvik, N.W.T., airstrip

The Inuvik airfield was constructed between 1956 and 1958 on a site underlain by frozen fine-grained soils containing considerable quantities of ice. Its design and performance were therefore of considerable concern. The airfield consists of an embankment of rock fill constructed on the undis-turbed...
