MnDOT Research Synthesis: Snowplow Blade Life Span

MnDOT Tranportation Research Synthesis: Joma Plow Blades
Client: Minnesota Department of Transportation - Research Services & Library
Audience: MnDOT managers and staff

In this Transportation Research Synthesis, CTC & Associates helped MnDOT investigate the cause of premature wearing on newer Joma carbide-insert snowplow blades compared with blades purchased in previous years. MnDOT was especially interested in determining whether pavement microsurfacing treatments might be reducing the blades’ life span. We conducted a literature review and surveyed agencies in Minnesota and other states, analyzing 92 survey responses to help assess the extent of the problem and identify possible causes.
