High-speed highway plowing requires cutting edges that clear wet snow and slush down to bare asphalt without damaging expensive road infrastructure. Traditional rigid steel blades can catch on raised pavement markers, manhole covers, and bridge expansion joints. Today, we examine why rubber JOMA style flexible blades are highly effective for high-speed highway maintenance.
Key Advantages of Rubber JOMA Style Blades on Highways
Rubber-encapsulated JOMA style blades integrate hard tungsten carbide inserts inside a resilient vulcanized rubber matrix, delivering unique benefits for highway fleets:
1. Protection of Road Infrastructure & Reflectors
Rigid steel edges snag on raised pavement markers (RPMs) and expansion joints, often tearing markers out of the asphalt and causing damage to the plow frame. The flexible rubber segments in JOMA style blades contour over obstacles, clearing snow smoothly without damaging road infrastructure.
2. Vibration Dampening for Driver Comfort
Plowing highways at speeds up to 30–40 mph causes continuous high-frequency vibration. The rubber casing absorbs impact shock waves before they reach the truck cab, significantly reducing driver fatigue during long shifts.
3. Superior Surface Conformity on Crowned Roads
Highway lanes are engineered with a central crown for water drainage. Rigid single-piece blades only scrape the high points, leaving streaks of slush in depressions. JOMA style articulated segments flex independently to hug road contours, achieving a complete scrape in a single pass.
High-Speed Performance Comparison
- Rigid Steel Blades: Fast surface clearing, but high noise, severe vibration, and frequent damage to pavement markers.
- Standard Rubber Blades: Quiet and safe for infrastructure, but wears out rapidly and struggles to cut packed ice.
- JOMA Style Rubber-Carbide Blades: Combines the ice-cutting power of tungsten carbide with the shock absorption of rubber for high-speed highway efficiency.
