Download or read book Best Management Practices for Environmental Issues Related to Highway and Street Maintenance written by William Albert Hyman and published by Transportation Research Board. This book was released on 1999 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to state, local, and federal agency environmental and maintenance administrators, directors, supervisors, engineers, and scientists. It describes current best management practices (BMPs) for environmental issues related to road and street maintenance. The synthesis documents relevant background and recent information with regard to management practices that can help protect, preserve, or enhance the environment while at the same time allow road maintenance organizations to carry out their fundamental mission of maintenance and repair in a cost-effective manner. Information for the synthesis was collected by surveying U.S. and Canadian state and local transportation agencies and by conducting a literature search using domestic sources. This report of the Transportation Research Board describes BMPs consisting of broad management approaches applicable to the entire maintenance program or to more than one program area. In addition, BMPs for specific maintenance activities or groups of maintenance activities are included. Finally, BMPs concerning specific environmental issues are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1997 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the symposium was to provide a forum for the exchange of information about state-of-the-art research and technology applications to improve snow removal and ice control operations in transportation systems. Sixty-one papers were presented in the areas of policy and management, infrastructure and snow control, materials and applications, equipment, travel surface, environment and health, road weather information systems and forecasting, and safety and visibility. Papers were authored by maintenance engineers and researchers from Austria, the Czech Republic, Denmark, Finland, Germany, Japan, New Zealand, the Netherlands, Norway, Russia, Sweden, the United Kingdom, and the United States. Twenty-one of these papers are included in this publication.

Available in PDF, EPUB and Kindle. Book excerpt: A laboratory study has been conducted with two aims in mind. The first goal was to develop a description of how a cutting edge scrapes ice from the road surface. The second goal was to investigate the extent, if any, to which serrated blades were better than un-serrated or "classical" blades at ice removal. The tests were conducted in the Ice Research Laboratory at the Iowa Institute of Hydraulic Research of the University of Iowa. A specialized testing machine, with a hydraulic ram capable of attaining scraping velocities of up to 30 mph was used in the testing. In order to determine the ice scraping process, the effects of scraping velocity, ice thickness, and blade geometry on the ice scraping forces were determined. Higher ice thickness led to greater ice chipping (as opposed to pulverization at lower thicknesses) and thus lower loads. Similar behavior was observed at higher velocities. The study of blade geometry included the effect of rake angle, clearance angle, and flat width. The latter were found to be particularly important in developing a clear picture of the scraping process. As clearance angle decreases and flat width increases, the scraping loads show a marked increase, due to the need to re-compress pulverized ice fragments. The effect of serrations was to decrease the scraping forces. However, for the coarsest serrated blades (with the widest teeth and gaps) the quantity of ice removed was significantly less than for a classical blade. Finer serrations appear to be able to match the ice removal of classical blades at lower scraping loads. Thus, one of the recommendations of this study is to examine the use of serrated blades in the field. Preliminary work (by Nixon and Potter, 1996) suggests such work will be fruitful. A second and perhaps more challenging result of the study is that chipping of ice is more preferable to pulverization of the ice. How such chipping can be forced to occur is at present an open question

Download or read book Final Report on Environmentally Sensitive Sanding and Deicing Practices written by and published by . This book was released on 1995 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth in the Denver-metro area has led to an increased impact on the environment due to winter maintenance activities. According to the Regional Air Quality Council, the use of sand as a traction aid contributes up to 45% of the particulate air pollution (PM sub 10) in the Denver area. The Environmentally Sensitive Sanding and Deicing Practices at the University of Colorado at Denver investigated literature and current practices from a wide variety of sources to arrive at a document which summarizes the current state of knowledge about deicing practices and their effect on human health and the environment. Topics include: properties of snow and ice, roadway traction, anti-skid materials, air quality impacts of anti-skid materials, water quality impacts of deicing chemicals, deicing chemicals, equipment to apply deicers, snow and ice management practices, and current practices obtained from interviews and site visits. Topics for further research are also discussed. This report recommends that the use of sand be reduced, that sand be swept up as soon as practical, that the use of alternative deicers be considered, that winter maintenance activities be timed for optimal efficiency, and that the Colorado Department of Transportation conduct technology transfer seminars around the State to increase awareness of environmental impacts.
