Update the AASHTO Guide for Snow and Ice Control

The AASHTO Guide for Snow and Ice Control, prepared under NCHRP Project 20-7(83) and published in 1999, provided a comprehensive guide for snow and ice control. As environmental awareness associated with snow and ice control grew, an update to the Guide was made in 2008 under NCHRP Project 20-7(250) to add content addressing environmental implications and impacts. Winter weather affects nearly every state not only by snowfall, but also ice events, freezing rain, freezing fog, and other weather events that impact mobility and require a maintenance effort to mitigate these effects. The range of winter maintenance operations is not limited to northern climates but includes weather regimes in moderate and maritime climates that require special considerations not currently addressed in the current AASHTO Guide. Advancements have been made in research and state of the practice in several areas, including (1) equipment: wing plows, belly plows, tow plows, liquid deployment systems, and brine making facilities; (2) strategies: Maintenance Decision Support Systems, plowing alternative lane configurations such as roundabouts and diverging diamond interchanges, and the utilization of fixed automatic spray technologies for specific locations and critical infrastructure such as structures; (3) deicing technology: liquids and liquid-only routes, utilization of slurry, various solid-liquid and liquid-liquid blends to enhance deicing performance; (4) Road weather information system (RWIS) and sensor technology: non-contact sensor technology, mobile RWIS, grip sensors; and (5) sustainability and resiliency in the delivery of service and procurement, storage, and deployment of materials. The objective of this research is to prepare, for publication by AASHTO, an updated guide for snow and ice control that addresses the advances in the state of the practice across a variety of climatological regions and provide guidance in the long-term planning necessary to be responsive to changing conditions. This objective will be accomplished by the following tasks: (1) Evaluate each existing chapter of the AASHTO Guide for Snow and Ice Control and include the best methods, practices, equipment, and technologies that have been developed; (2) Consider new sections in the Guide to address new strategies, tactics, and technologies that have been developed and are routinely utilized during winter maintenance operations, and (3) Ensure that the Guide covers strategies that address all weather regimes across the United States from northern snow belt to windswept plains to moderate/maritime ice belt states.
