Experimentation of several mitigation methods in Tasiujaq Airport to minimize the effects caused by the melting of permafrost
Since the beginning of the 1990s an important increase in the mean annual air temperatures has been recorded in Nunavik, Québec, Canada. This has lead to the degradation of permafrost, which is threatening the stability of airport and road embankments in the region. In the summer of 2007 a test-site...
