Book Synopsis Prevention and Control of Culvert Icing by : Kevin L. Carey
Download or read book Prevention and Control of Culvert Icing written by Kevin L. Carey and published by . This book was released on 1975 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Application of Electrical Energy to Culvert Icing Problems by : David A. Gaskin
Download or read book Application of Electrical Energy to Culvert Icing Problems written by David A. Gaskin and published by . This book was released on 1974 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A laboratory study was made to investigate the use of electric heat cables to counteract culvert icing. An automatic system for producing a thaw tunnel of a preselected diameter was developed and tested. An 80-in.-long, 1 ft-diam culvert with a 10 ft copper sheath heating cable modeled a typical Alaskan installation. Tests were made to evaluate several continuous power levels, a short-term percentage timer, and the automatic system. Maximum efficiency (cross section produced/unit energy input) occurred when the cable was operated continuously at its maximum permissible power level. The short-term timer system was less efficient than applying the same amount of energy continuously. The automatic system performed well in the laboratory, but may need additional design work to ensure high reliability in field applications. (Modified author abstract).

Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
