Performance of the Beaver Creek Section of the Alaska Highway
The construction of transportation infrastructures in permafrost conditions affects the thermal regime of frozen ground and may cause deterioration of the permafrost. If the pavement foundation is constituted of ice-rich permafrost, the structural and the functional capacity of the infrastructure will be affected. Moreover, pavements that have always been stable over permafrost now begin to become unstable as a result of the observed trend toward a global warming of the planet. This is becoming an important engineering problem for northern transportation infrastructures. Several techniques have been developed and experimented to protect pavements from permafrost degradation. However, few of these techniques have been widely adopted in current construction practice. The project is intended to provide guidance to Yukon Highways and Public Works and other interested Canadian highway agencies on possible adaptation scenarios. The objective was to propose and document cost-effective adaptation scenarios for Alaska Highway as well as other Yukon highways to permafrost degradation resulting from global warming. The project involves a comprehensive literature review on deterioration mechanisms and on protection techniques. It also involves the analysis of the thermal regime of an instrumented section of the Alaska Highway near Beaver-Creek YT. The paper will focus on the results on the thermal analysis and on recommended adaptation scenarios.
