摘要：	This report presents the evaluation of winter maintenance efforts, including applications of deicers and anti-icers and plowing, in parallel conditions on actual pavements to assess intuitions based on observations and anecdotal evidence. Parallel conditions eliminate the issue of test sections being in slightly different geographies. Three different aspects were evaluated in this effort: (1) Deicer effectiveness, techniques and materials evaluated at two proximal facilities across parallel treatment lanes of up to 1,000 feet in length; (2) Plow effectiveness, techniques and equipment evaluated at the same locations as the deicer effectiveness evaluation; and, (3) Anti-icer persistence, measured in response to both: actual traffic through drainage off defined roadway sections of an elevated highway; and precipitation through drainage off asphalt and Portland cement concrete pavements in a laboratory setting. Results of this work indicate factor interaction such as truck traffic plus deicer use or roadway crosswind and deicer distribution may have significant impact on differences in winter maintenance performance and deicer efficiency.
