Performance and Cost-Effectiveness of Thermal Stabilization Techniques Used at the Tasiujaq Airstrip
The Tasiujaq airstrip in Kuujjuaq, Nunavik (Canada) is affected by permafrost degradation. As a result, the runway requires intensive maintenance in order to maintain a good service level. Three protection techniques, an air convection embankment, an embankment with an integrated heat drain and an embankment with gentle slope, have been tested in the shoulder of the Tasiujaq airfield. The purpose of this study is to assess the technical feasibility of installing those systems, to validate through testing in real operating conditions, their respective performance and to assess their cost benefit. Those techniques increase heat extraction from the soil and thus preserve integrity of permafrost existing under the runway. This paper summarizes the results of the study and discusses operational constraints and cost effectiveness of the thermal stabilization techniques tested at the Tasiujaq airstrip.
