Abstract

A roadway for use on permafrost terrain is described together with methods of construction, the roadway generally including a porous embankment and a pavement structure disposed on the top of the embankment. The embankment has a desired vertical separation between the bottom and the top of the embankment and comprises material of sufficient permeability to allow buoyancy-driven pore air convection to occur within the embankment when an unstable density stratification exists therein. This unstable density stratification occurs in the winter months when a temperature differential between the top of the embankment and the ground adjacent the bottom of the embankment exists, whereby the roadway promotes natural convection within the porous embankment which enhances heat removal from the embankment and underlying ground to preserve the permafrost layer throughout the year.
