Abstract	The thermal performance of a shallow road embankment constructed on permafrost in the discontinuous zone of the Mackenzie Valley was monitored over a 5-year period. The shallow (1.2 m) embankment consisted of clean borrow material end dumped on a right-of-way which had previously been cleared of trees. The road was never opened to general traffic; consequently snow removal was minimal. Measurements included hourly ground temperatures recorded with a data logger operating unattended. Settlements were monitored and thermal conductivity probes were installed to yield information on seasonal trends within the embankment and in the various natural materials comprising the active layer. The data indicate that degradation of the permafrost is under way and provide information on the relation between road surface temperatures and climatic factors for this region.
