Abstract:

This report concerns the use of thermal insulation under rigid pavement. It is recognized that the desirability of preventing soil freezing applies equally to the supporting subgrade for flexible pavement. The exact placement of the insulation under either type of pavement will depend upon individual job requirements and the ingenuity of the designer. It should be kept in mind that the installation method and its compatibility with standard construction procedures is an important factor in the cost of the project. If the installation method is complicated, it will likewise be costly. In this event, the use of thermal insulation may not prove economical in comparison with the conventional practice of replacing the frost-susceptible subgrade soil with granular material.
