Prevention and Control of Culvert Icing

📖 The Scoop

U.S. Army Cold Regions 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 by 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.
