Book excerpt: "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 excerpt: This report contains 56 conference papers pertaining to snow removal and ice control research including Canadian research and equipment. Several of the papers are concerned with deicing salts--their effectiveness, their impact on the environment, and possible alternatives to them. Alternative methods of deicing discussed herein include: heating of bridge decks, increasing coefficient of friction between tires and pavement surfaces, use of high intensity lights, and advent of less corrosive chemicals. There are also several papers that address the problem of snow and ice accretion on power wires, guideway systems, sign boards, and etc. There is considerable attention given to development of computer programs and models for predicting scope of snow and ice control operations and for evaluating their effectiveness. Also, several papers discuss new developments in snow removal equipment and the cost of operation and maintenance.

This book was released on 2006 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study addressed pretreatment protocol for winter maintenance of roadways using brine. Information regarding pretreatment was assessed from surveys of personnel in state departments of transportation and county garages in Ohio. Field durability studies of various applications of brine were conducted on Portland cement concrete and asphalt concrete pavements in Ohio. Over three winter seasons, weather events and resulting pavement conditions were documented during pretreatment and during the subsequent events using visual and limited road grip tester (RGT) assessment. In addition, extensive laboratory studies were undertaken to supplement the field investigations. Integration of the findings resulted in a decision tree to aid in operational planning and pretreatment.

This book was released on 2017 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large amounts of salts are applied every winter to highways, streets, parking lots and sidewalks. Despite its effectiveness, the use of salt has increasingly become a public concern because of the detrimental effect it has on the environment and the corrosion it causes to infrastructure and vehicles. Transportation agencies therefore are actively seeking ways to reduce salt use while keeping their roads safe. As an alternative to regular salt, new chemicals and additives, mostly agriculture byproducts or agro-based organic alternatives, that have fewer environmental side effects than regular road salts, are being developed by the industry and are increasingly available in the market. However, information on the field performance of these new organic alternatives as compared to regular salts is still limited. Questions concerning optimal application rates, mixing ratios, and the role of weather and traffic conditions still need to be answered for some newly available products. In this study, two organic agro-based products, namely, Fusion and Geomelt, for deicing/anti-icing treatments, were selected and their performance was tested through a series of field tests. The goal of this research is to investigate how well they would perform in field as compared to regular salt brine. A field test was conducted to collect performance data of these materials when used in prewetting and anti-icing operations. A total of nine snow events were covered in this experiment. The maintenance treatments that were tested followed the common maintenance operation protocols recommended by the two municipalities. Traction levels and visual conditions were used as the main performance metrics along with other road weather and pavement condition data. Three main findings were obtained from an analysis of the test data. First, salts prewetted with these organic compounds performed similarly to those using regular salt brine. In most cases, the performance differences were not statistically significant, indicating that there was little evidence supporting the superiority of the organic materials for a prewetting purpose. The test data also indicated that this was true under low temperatures (~-10°C), contrary to the common beliefs about the performance of these products. However, it should be noted that performance similarities could also be influenced by the fact that the organic liquids were used for prewetting salt at a much lower ratio (5% vs. 20% for brine). Also, the dominant compound in these prewet mixes is still regular salt - sodium chloride (95% for organic treated salt and 85% for brine treated salt). When used for prewetting purposes, Geomelt and Fusion showed similar performance in terms of traction level. However, when used as additives to brines for Direct Liquid Application (DLA), both organic products largely outperformed pure salt brine despite being applied at a half its application rate. Field tests also showed that the tested compounds could help maintain up to 20% higher traction and could maintain safer friction levels for up to an hour longer. Fusion outperformed Geomelt by up to 10 % in terms of traction level. Lastly, in general the sections treated with DLA performed significantly better than the untreated sections, confirming the advantage of anti-icing strategy for snow and ice control. The field data was further used to estimate a performance model that can be used by maintenance practitioners facing similar conditions. Two different models were explored, the first set of models focused on assessing the relative snow melting rate of Geomelt and Fusion as compared to regular brine. In its final form, the model suggests that the difference in the friction number on a surface maintained with Fusion or Geomelt and one maintained with Brine will increase at a rate of 1.76 per hour and 1.95 per hour respectively on identical test sections if no further maintenance actions are taken. The second set of models estimated were general purpose models that can be used to estimate the friction level on a roadway after maintenance has been conducted. In these models, the effects of weather, wind, and chemical type were found to be significant.
