Hello! and Welcome to the exciting world of road construction, Permafrost, and all the wild and crazy  things that happen when the two are combined.  Building safe, adequate, durable roads over permafrost soil presents unique challenges to the construction industry. It is not suprising that the mechanisms that lie behind these challenges are explained by the laws of physics. Consequently, as concerned professionals from the engineering community look for inovative ways to deal with the permafrost specter, it is in the realm of physics where they look for the elusive techniques that will enable the extension of the transportation infastructure into the northcountry in a safe, efficient, wize, and economic way. This web site will explore the techniques used to build road embankments over frozen soil. In exploring these techniques, every effort will be made to demonstrate the physical concept that is pertinent. But-prior to our examination of diferent methods of permafrost resistent roadbuilding techniques we must start by going back to basics. To understand the construction methodology of arctic roadbuilding we need to understand the mechanics and properties of permafrost. CLICK HERE to unlock the mysteries of what permafrost is.
