ABSTRACT: In order to better understand permafrost degradation on transport infrastructures, 12 experimental sections have been constructed on the Alaskan Highway near Beaver Creek. These sections experiment one or several combined methods of thermal stabilization such as convection air embankment, heat drains, grass-covered embankment, reflecting surfaces and snow clearing on embankment slopes. To rigorously monitor the temperature evolution for the next years and to determine the efficiency of theses text sections, thermistor cables have been installed into the shoulder and at the center of the embankment.
RÉSUMÉ: Afin de trouver des solutions pour contrer les problèmes engendrées par la dégradation du pergélisol sur les infrastructures routières, 12 sections d'essais ont été construites sur l'Alaska Highway près de Beaver Creek. Ces différentes sections d'essais expérimentent des techniques de stabilisation thermique utilisées seules ou combinées, telles que le drain thermique, le remblai à convection d'air, le remblai couvert de matière organique, la surface réfléchissante ainsi que la protection contre les effets isolants de la neige. Afin d'effectuer un suivi rigoureux de l'évolution du pergélisol durant les prochaines années pour ainsi déterminer l'efficacité des sections, des chapelets de thermistances ont été installés dans l'épaulement du remblai ainsi que sous le centre de la route. 1 INTRODUCTION
