The Influence of Insulation upon Frost Penetration Beneath Pavements
Frost action in soils causes pavement structures to heave because of ice lense growth during the freezing season. The loss of structural support in the spring caused by melting of the ice lenses can precipitate pavement failure. In order to minimize differential frost heaving caused by variable in-s...

Frost action in soils causes pavement structures to heave because of ice lense growth during the freezing season. The loss of structural support in the spring caused by melting of the ice lenses can precipitate pavement failure.

This creates a uniform layer to bridge subsurface irregularities in soil properties. The thickness of uniform granular material depends on the depth of frost penetration and desired protection. This method of protecting the pavement structure from differential (uneven) heaving can be costly depending on the amount of granular material required and its availability. A method of reducing the amount of granular material is the use of a thermal insulating layer beneath all or part of the base course which prevents freezing temperatures from reaching the non-uniform subgrade.
