Performance of Insulated Pavements at Newton Fields, Jackman, Maine
In 1986, the runway at Newton Field, a small airport in Jackman, Maine, was reconstructed using a 2-inch thick layer of extruded polystyrene insulation as part of the pavement structure. At the same time, a nearby town road was reconstructed using a conventional uninsulated pavement cross section for relatively heavy loads. Both pavements were monitored for frost penetration, frost heave, and seasonal changes in pavement strength. Since frost penetration beneath the insulation layer of the runway at Newton field exceeded empirical estimates during the winter of 1986-1987, four additional test sections with varying combinations of insulation and subbase thicknesses were constructed adjacent to the airport's parking apron during the summer of 1987. Although the thermal performance of the insulated pavement test sections was comparable to design expectations for the following three years, evidence of discontinuities in the insulation layer in the Newton field runway demonstrates the insulated pavements' susceptibility to variations in construction. Discussed here is pavement performance at each of the test sites over the observation periods 1986-1990 and 1987-1990.
