Source Year Type Jurisdiction Findings
Evaluation of Snow Plow Blade Systems, Final Evaluation 2011 Research report North Dakota DOT Joma blades lasted three to four times longer than carbide steel, although in the test one truck experienced a reduction in Joma blade service life when the blade angle was set incorrectly on the plow.
“Maintenance testing new blades,” Inside newsletter 2009 Anecdotal report Iowa DOT Blades tested in 2000 lasted an average of three times longer than steel blades, although Iowa didn’t implement them at the time due to cost
Joma Plow Blade Evaluation 2010 Research report Lake County, Ohio Joma blade life span averaged 6,000 miles since they were first installed on the county’s plows in 2005 compared to 1,000 to 1,500 miles for steel blades
2010 Research report Franklin County, Ohio Trucks equipped with steel blades required an average of 2.6 blade changes in the 2006-2007 winter season. During the 2007-2008 winter season, trucks equipped with Joma blades required an average of 0.5 blade changes, suggesting five times as many blade changes for steel blades as Joma blades, although service time and mileage were not reported.
New Hampshire DOT 2009 Annual Report 2009 Anecdotal report New Hampshire DOT Projecting from five months of testing from the winter of 2008-2009, New Hampshire’s District 6 determined that Joma blades would last eight times as long as the department’s current blades. Further testing was planned for the 2009-2010 winter, but it did not happen due to the mildness of that winter
Clear Roads Product Experience Feedback for 2006-2017 Winter Seasons 2009 Anecdotal report Illinois DOT One Joma blade outlasted two sets of carbide blades in a single test. Follow-up comments in 2011 and 2012 reported that increased life span had continued.
2008 Anecdotal report Milaca and Elk River, Minnesota On one route, consisting of 14 miles of seal coat, 10 miles of microsurfacing, 5 miles of nova chip and 5 miles of bituminous, a Joma blade lasted 108 hours before replacement. A second route, consisting of 18 miles of seal coat, 25 miles of bituminous, 7 miles of concrete and 9 miles of microsurfacing, a Joma blade lasted 85.5 hours. On a third route, which was 45 miles of concrete in poor condition, a Joma blade lasted only 40 hours.
2007 Anecdotal report Utah DOT In two tests, Joma blades lasted 124 hours and 108 hours compared to an average of 21 hours for traditional blades.
