Title:

Documentation of Liquid De-icing Agents Utilized during the Winter of 2005-2006

Abstract:

During the winter of 2005-2006, the Maine Department of Transportation (MaineDOT), Bureau of Maintenance and Operations experimented with several liquid de-icing products designed to pre-wet granular materials. This experimentation was undertaken in an effort to determine which liquid de-icer would be the most suitable replacement for the calcium chloride (LiquiDow) product previously used by the Department. LiquiDow is no longer available from the supplier who was providing the product. It is unclear at this time if LiquiDow can be obtained from one of the other suppliers in the industry. A process was subsequently developed to document the results experienced by the Departments Highway Maintenance crews. Several Crew Supervisors from each Region, representing a cross-section of opinions, were interviewed as part of this process. A list of 10 questions (attached) was used to initiate an informal discussion with each group. Results of these discussions, summarized by Region, are included in Appendix A.
