FROZEN SUBBASE: KEEP IT COOL, KEEP IT STRONG

In 1969, the Alaska Department of Transportation and Public Facilities (Alaska DOT) constructed the first insulated runway over permafrost in North America at the Kotzebue Airport. Extruded polystyrene insulation proved to be the most cost-effective, high performance product to solve the problem of permafrost degradation. Styrofoam (Trademark) brand plastic foam, a closed-cell extruded polystyrene foam, was chosen for its superior water resistance, long lasting R-value, and the high compressive strength needed under the runway. This article describes the installation and performance (expected and actual) of the Styrofoam.
