Abstract: The purpose of this paper is to outline the state-of-the-practice in cold regions earthwork based on experience gained in the Prudhoe Bay area of Alaska. Material properties of fill used for various cold regions engineering applications are addressed. Methods of assessing potential material sources, including landform analyses, borings, and geophysics are briefly discussed. The techniques used for excavation, including blasting, ripping, and scraping are a function of the material characteristics of the sources utilized. Hauling equipment is dependent on the volume of material to be hauled and the type of material developed at the borrow source. This paper discusses these relationships. In addition, embankment use, material type, and placement and compaction techniques are addressed.
