Book Description
"This synthesis report will be of interest to transportation agency maintenance engineers, managers, and operators and others involved with roadway snow and ice control including safety engineers, traffic engineers, and law enforcement agency personnel. It presents information on the state of the practice in managing roadway snow and ice control considering both rural and urban locations. The document describes the developments that have occurred during the past 20 years to improve winter maintenance. This report of the Transportation Research Board discusses winter maintenance policies and provides examples for state, city, and county agencies. Included in the discussion of winter maintenance policies are issues such as: levels of service, public relations, liability for services, and experimenting with new policies. Additional information is included on estimating winter maintenance benefits and costs; personnel and management issues; weather information systems; and materials, equipment, and facilities for winter maintenance."--Avant-propos.

Book Description
Surveys of highway connected agencies and an extensive literature search of maintenance research in the U.S., Great Britain, and Europe were conducted to compile a review of existing nonchemical methods of snow removal and ice control of concrete surfaces. Details of permanent installations, the water pipe and electrical heating element customarily installed in concrete slabs, are given. Potential applications of electrical and gas-fired infrared heaters are discussed. other methods investigated included covered bridges, electrically conductive road surfaces, snow melting pits, and bridge deck insulation.

Book Description
The first and only comprehensive guide to best practices in winter road operations Winter maintenance operations are essential to ensure the safety, mobility, and productivity of transportation systems, especially in cold-weather climates, and responsible agencies are continually challenged to provide a high level of service in a fiscally and environmentally responsible manner. Sustainable Winter Road Operations bridges the knowledge gaps, providing the first up-to-date, authoritative, single-source overview and guide to best practices in winter road operations that considers the triple bottom line of sustainability. With contributions from experts in the field from around the world, this book takes a holistic approach to the subject. The authors address the many negative impacts on regional economies and the environment of poorly planned and inadequate winter road operations, and they make a strong case for the myriad benefits of environmentally sustainable concepts and practices. Best practice applications of materials, processes, equipment, and associated technologies and how they can improve the effectiveness and efficiency of winter operations, optimize materials usage, and minimize cost, corrosion, and environmental impacts are all covered in depth. Provides the first up-to-date, authoritative and comprehensive overview of best practices in sustainable winter road operations currently in use around the world Covers materials, processes, equipment, and associated technologies for sustainable winter road operations Brings together contributions by an international all-star team of experts with extensive experience in designing, implementing, and managing sustainable winter road operations Designed to bring professionals involved in transportation and highway maintenance and control up to speed with current best practice Sustainable Winter Road Operations is essential reading for maintenance professionals dealing with snow and ice control operations on highways, motorways and local roads. It is a valuable source of information and guidance for decision makers, researchers, and engineers in transportation engineering involved in transportation and highway maintenance. And it is an ideal textbook for advanced-level courses in transportation engineering.

Book Description
Geothermal energy has been applied to a snow melting system for highway overlays. This paper described practical steps for the design, construction, and validation of the system. These steps were carried out both in a laboratory and in the field. In the laboratory, a series of heat conductivity tests were carried out to understand the heat transfer characteristics in a pavement layer and to determine an optimum pipe pitch at 50 mm depth. Steel fiber reinforced concrete (SFRC) was proposed as the pavement material to make the system durable in overlays subjected to heavy traffic, and its resistance to construction cracks was tested in the field. In 2009, the first trial version of the geothermal snow melting system was built into a 50 mm thick SFRC overlay. Since then, its snow melting performance has been monitored and evaluated under different snowfall accumulations and intensities. Given the design variables, it took about 30 to 60 minutes to remove snow and ice even under heavy snowfalls. Finally, the construction and operation costs of the developed system were calculated and compared with those of other snow melting methods. It is expected that the developed system will be installed on tunnel entrances and bridge decks on highways once its durability is verified under heavy axle loads.
