Specifications include, but are not limited to: a) The Contractor shall have a working knowledge of anti-icing strategies for minimizing and preventing the bonding of snow and ice to the pavement surface. The Contractor shall utilize calibrated spreading equipment to implement the anti-icing strategies responsibly and effectively. Information on anti-icing may be found at the MaineDOT web site as follows: http://www.maine.gov/mdot/winterdriving/snowicecontrol/ b) The Contractor shall commence plowing and material application operations no later than when snow on the pavement has reached a depth of one-half to one inch if the snow is wet and one to two inches if dry. Snow will be plowed and salt and/or winter sand will be used as needed during the storm to keep the roads open to traffic, to prevent bonding of snow and ice, and to provide a good surface upon which to operate. During the storm, or subsequent drifting, plows shall be operated to maintain two-way traffic and average cycle times of approximately 2 hours. Between the hours of 10:00 p.m. and 4:00 a.m., the average cycle times may increase when storm conditions allow reasonably safe travel on the roads and strategic use of winter sand may be utilized to help carry low traffic volumes during these extended plow cycles. Immediately after the storm conditions have subsided, snow shall be removed to just beyond the outside of the shoulders of the highway to allow proper drainage and onethird bare pavement shall be provided in the middle of the road as soon as practicable. In most cases, this will occur within thirty (30) hours of the end of storm. c) The Contractor shall use appropriate methods and practices of plowing and material application to ensure continuity of operations with adjacent plow routes that may be addressed by municipal forces, state forces, or other contractors, as well as other plow routes in the same geographic area that have the same corridor priority (the Department’s Representative may be contacted for clarification of which roads in the area share a similar priority level). The Contractor shall also ensure that the speed of their plowing operations is low enough to produce efficient plowing and material use and that appropriate care is taken to minimize the potential for damage to State and personal property adjacent to the highway (such as guardrail, curbing and mailboxes, etc.).
