Abstract
Ilulissat Airport was constructed in 1982 to 1984 after detailed geotechnical investigations as the construction site
included up to 12 m thick basins of marine clay deposits. Despite soil temperatures of approx -3oC the soil appeared
unfrozen from 4 to 5 m below ground surface due to a high residual salt content in the porewater. However, in the less
saline top zone massive ice layers was found constituting up to 30 volume%. These formations representing a type
example of saline permafrost caused the planned position of the runway to be shifted towards northwest and a removal
of the layers and substitution with compacted blasted rock fill. However, a test fill of 2.5 m of rock fill and coarse
gravel was constructed in the abandoned area in order to establish experiences for future constructions. Background
and previous findings will be covered and present activities are topics in a companying paper.
