VDT-V88 Deflector Central RH RM87966826 Front Fender Screed Plate Deflector 80632482 for Asphalt Paver Spare Parts

The deflector is an adjustable plate or blade located near the screed's front edge (often integrated with the strike-off plate). It controls the flow and distribution of hot mix asphalt (HMA) to prevent:

• Material surge (uneven pile-up ahead of the screed)
• Segregation (separation of coarse/fine aggregates)
• Excessive head pressure (which can distort mat smoothness)

• Adjustability: Angle can be manually or hydraulically adjusted to match material viscosity and paving speed. Example: Steeper angles for high-viscosity mixes (e.g., polymer-modified asphalt)
• Material: Hardened steel or tungsten carbide edges to resist abrasion
• Integration: May work with augers and tamper bars to ensure uniform material feed

• Too high: Causes insufficient material feed, leading to mat tearing
• Too low: Creates excessive resistance, causing ripples or uneven compaction
