Winter maintenance agencies are continually searching for the perfect plow blade: durable, long-wearing, cost-effective, and effective in a range of conditions. Stainless steel and carbide-insert blades are staples of most DOTs’ fleets, and agencies test new products each year, like flexible blade assemblies designed to conform to the roadway surface.
A sampling of state specifications for plows and plow blades.
Every year, Clear Roads member states share the results of pilot-testing of winter maintenance products and materials that their agencies have conducted.
