RADAR PROFILING OF NEWTON AIRFIELD IN JACKMAN, MAINE

During April 1987 ground-penetrating radar was used to observe subsurface conditions of Newton Field, an airfield in Jackman, Maine. It was constructed in 1986, with insulation used as part of its subgrade. A road near the airfield that was constructed in the same fashion, except without the insulation, was also profiled for comparison. The survey was to document conditions of nonuniform frost heaving and, if possible, frost depth. Radar data, collected with a 900-MHz antenna, showed that the insulation beneath the runway apparently varied in depth from approximately 5 to 24 in. Frost depth, however, could not be determined with the 900-MHz antenna.
