Description :
This paper gives examples of geomorphic elements affecting road construction in a cold environment : eskers, drumlins, plains of late and postglacial glaciolacustrine and marine sediments, mires, steep rock cliffs, river channels and ice-dams, fluvial erosion, and palsas. Solutions to these problems include removal of frost sensible materials and replacement by more favorable sediments. Road surfaces, kept snow-free in the wintertime, are subjected to deep freezing. Some examples of how road construction affects geomorphic processes and vice versa are provided.
