U.S. Army Cold Region Research and Engineering Laboratory field inspections and data collection on icing conditions and methods of control prior to 1966 provided background to the overall study. A literature survey, covering primarily American and Russian experience, and a survey be questionnaire of highway maintenance forces in Alaska provided background to a field study of icing prevention and control covering four winter seasons in Alaska. Climatological, culvert temperature, ground temperature and hydrologic data were collected at Grenac, Steele and Flume Creeks near Fairbanks, Alaska, to extend understanding of icing phenomena. Field trials were conducted at Bear Creek, Grenac Creek, Steele Creek, Moose Creek and Gakona Spring to test three expedient techniques for controlling icing: electric heating cables, channel improvement and channel covers. Electric heating cables and channel deepening proved to be very promising for icing control, and improved installation and operating procedures for electric heating cables were developed during the study. The usefulness of channel covers proved to be rather restricted. Ground temperature data were collected from an array of thermocouples beneath and adjacent to a 24-in. corrugated metal culvert at Mile 15 on the Elliott Highway to study the thermal regime surrounding an ice-flooded culvert. These data demonstrated that culvert ends were the critical regions of heat loss.
