Overview

EN 500-3:2006+A1:2008 (CEN) - "Mobile road construction machinery - Safety - Part 3: Specific requirements for soil‑stabilising machines and recycling machines" is a Type C safety standard that supplements EN 500-1 (Common requirements). It specifies safety requirements addressing significant hazards for mobile soil‑stabilising and recycling machines during intended use and reasonably foreseeable misuse. The document includes Amendment 1 (2008) and aligns with CEN procedures and EU machinery directives.

Key topics and technical requirements

• Scope and definitions: Defines soil‑stabilising machines, recycling machines and mixing equipment used to mix fillers/binders with soil or reused pavement material.
• Operator protection: Operator’s stations for soil‑stabilising machines must provide a cab to protect against dust from the mixing process.
• Mixing equipment guards:
  • Mixing drums must be safeguarded to prevent contact and retain ejected debris.
  • Guards must comply with EN 953 requirements and remain permanently attached, even when opened.
  • Rear‑guard geometry guidance is given (e.g., certain clearances h and s in the standard).
• Side panels and controls:
  • Power‑operated side panels used during operation must use hold‑to‑run controls (no locking except neutral), be located out of danger areas, activate a yellow flashing light when operated, and auto‑return to preset position when released.
• Stopping and braking:
  • It must be possible to stop mixing equipment while the engine runs.
  • Braking systems for wheeled machines must meet the performance and test procedures in Annex A.
• Access and maintenance:
  • Lowest access step may be up to 700 mm above ground; the lowest up to three steps may be laterally flexible if mounted as a unit.
  • Elevating devices require locking devices for safe maintenance; hydraulic load‑holding devices should comply with ISO 8643.
• Other hazards covered: Pressurised systems, fire protection, hot surfaces, electrical/EMC, noise and vibration (referenced noise test code Annex B), conveyors, signals and warning signs (example: permanent “Warning! Rotating mixing drum” marking).

Practical applications and users

Who uses EN 500-3:

• Manufacturers and designers of soil‑stabilising and recycling machines for compliant design and CE marking.
• Safety engineers, certifiers and notified bodies performing conformity assessment and risk evaluation.
• Fleet owners, operators and maintenance teams to guide safe operation, operator training and retrofit/maintenance procedures.
• Regulators and procurement specifying machine safety requirements for road construction projects.

Benefits: ensures consistent safety measures, supports compliance with EU machinery directives (see Annex ZA/ZB), reduces operator risk from dust, rotating parts and maintenance activities, and provides test/verification guidance.
