BACKGROUND: The AASHTO Guide for Snow and Ice Control was published in 1999. This guide was intended to provide a training tool to help operators, supervisors, and managers select and implement methods or technologies to effectively deal with snow and ice conditions and provide road users with safe conditions and timely information to make trip decisions. However, substantial changes in the state of practice of snow and ice control have occurred since the publication of this guide as a result of advancements in plowing equipment, materials handling and storage, communications, technology, strategies, and other aspects of snow and ice control and management. Also during this period, substantial research on the different aspects of snow and ice control operations has been performed. Because of these changes as well as the environmental implications, budgetary and work force constraints, and the relevant research findings, there is a need to produce a guide that recognizes these issues and provides updated information and guidance on all aspects of snow and ice control operations. Such a guide will help highway agencies and other organizations address relevant issues and perform snow and ice control operations more effectively.
OBJECTIVE: The objective of this research is to develop a guide that will serve as the primary source for guidance on all aspects of snow and ice control operations. The guide is intended for adoption/publication by AASHTO and will supersede the 1999 AASHTO Guide for Snow and Ice Control, and other guidance on snow and ice control operations.
Accomplishment of the project objective will require at least the following tasks.
Phase I: (1) Review the AASHTO Guide for Snow and Ice Control, related literature and research findings, and other information relevant to snow and ice control operations (e.g., equipment, materials, technology, and strategies) to identify a scope for the proposed guide. This information may be obtained from published and unpublished sources and contacts with practitioners. (2) Based on the information gathered in Task 1, propose an updated research plan to be executed in Phase II to develop a guide that addresses all aspects of snow and ice control operations and serves as the primary source of guidance to the winter maintenance community. The plan shall include a tentative outline of the proposed guide. (3) Prepare an interim report that documents the research performed in Tasks 1 and 2 and includes the updated research plan for Phase II. Following review of the interim report by the panel, the research team will meet with the project panel. Work on Phase II of the project will not begin until the interim report and the Phase II research plan are approved by the NCHRP. The decision on proceeding with Phase II will be based on the contractor’s documented justification of the updated research plan.
Note: The research plan prepared in Task 2 must include a detailed outline of the proposed guide, a description of each proposed chapter, and a proposed delivery schedule for each chapter. The work proposed for Task 4 must be divided into subtasks, and proposers must describe in detail the work proposed for each subtask.
Phase II: (4) Execute the plan for developing the guide. Develop a draft version of each chapter and submit, as they are completed, for NCHRP review. (5) Assemble all chapters in a coherent document to serve as a draft version of the proposed guide. (6) Prepare and submit a final deliverable that documents the entire research effort and includes (1) a research report documenting the work performed in the project and used to develop the guide and (2) a stand-alone proposed Guide for Snow and Ice Control Operations.
Note: The individual chapters prepared in Task 5 shall be submitted for review as work progresses. Reviewers' comments shall be incorporated in revising these chapters and in developing other chapters.
STATUS: Research in progress.
