by frost heaving in the ground. The frost heave damages the ground in two ways. The first is because of the frost heaving itself, and the second is because of the decrease in the bearing capacity on the subgrade soil and the subbase courses during spring thaw. A number of methods are available to protect pavement from frost-heave damages.
