Description: CRREL Report
Abstract: Since 1975 the U.S. Army Corps of Engineers, the Federal Highway Administration and the Federal Aviation Administration have been working cooperatively to develop a mathematical model to estimate frost heave and thaw weakening under various environmental conditions and for various pavement designs. A model has been developed. It is a one-dimensional representation of vertical heat and moisture flux, is based on a numerical solution technique termed the nodal domain integration method, and estimates frost heave and frost penetration reasonably well for a variety of situations. The model is now ready for additional field evaluation and implementation in appropriate cases. The main objectives of this report are: 1) to describe the model, FROST, including modeling uncertainties and errors; 2) to summarize recent comparisons between measured and computed values for frost heave and frost penetration; and 3) to describe parameters necessary for input into the model.
