Roadway Design in Seasonal Frost Areas
Abstract
Highway engineers in seasonal frost areas have been aware for decades of the damaging effects that frost in the underlying support materials can have on pavement performance. The report of the Transportation Research Board describes and assesses the merit of current practice in roadway design in seasonal frost areas. Information is presented on the mechanisms of frost heaving and thaw weakening, the factors that contribute to frost problems, criteria for estimating frost susceptibility, surveying practices for locating areas of detrimental frost action, subgrade treatment and drainage to minimize the effects of frost action, and the structural design of pavements to accommodate the influences of frost action. Research needs in the area are identified.
