Component Specifications

Definition
The screed plate is a flat, heated metal plate mounted at the rear of an asphalt paver that spreads, levels, and provides initial compaction to asphalt material. It adjusts for thickness and crown, uses vibration or oscillation for density, and maintains temperature to prevent material sticking, ensuring uniform pavement surface quality.
Working Principle
The screed plate operates by floating on the asphalt mat, using its weight and adjustable angle to control thickness. It applies vibration or oscillation to compact the material, while heating elements maintain optimal temperature for workability and adhesion prevention, resulting in a smooth, dense pavement layer.
Materials
Typically made from high-strength, wear-resistant steel (e.g., AR400 or Hardox) with heat-treated surfaces. May include nickel or chromium coatings for durability. Heating elements are embedded or attached, using electric or propane systems.
Technical Parameters
  • Width 2.5m to 16m
  • Weight 200 kg to 2000 kg
  • Thickness 15mm to 40mm
  • Compaction Force Up to 30 kN/m
  • Operating Temperature 120°C to 160°C
Standards
ISO 15642, DIN EN 500-1

Engineering Analysis

Risks & Mitigation
  • Material sticking due to inadequate heating
  • Wear from abrasive asphalt
  • Thermal stress cracking
  • Improper leveling leading to uneven pavement
FMEA Triads
Trigger: Insufficient heating or temperature control
Failure: Asphalt adheres to plate, causing surface tearing
Mitigation: Regular calibration of heating systems and use of temperature sensors
Trigger: Abrasive wear from aggregate
Failure: Reduced plate thickness and compromised leveling accuracy
Mitigation: Use wear-resistant materials and apply protective coatings

Frequently Asked Questions

What is the purpose of heating the screed plate?

Heating prevents asphalt from sticking to the plate, ensures smooth material flow, and maintains workability for consistent pavement quality.

How does the screed plate adjust for pavement thickness?

It uses hydraulic or mechanical systems to change the angle of attack, allowing precise control over asphalt mat thickness from 20mm to 300mm.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
