A bulldozer is working on a long, continuous cut and fill operation where material needs to be transported consistently. If the initial pass establishes a slot 3 metres wide, and the operator aims to maintain maximum efficiency, what should be the approximate width of subsequent passes within the established slot to prevent unnecessary spillage and ensure consistent material flow?

Question: A bulldozer is working on a long, continuous cut and fill operation where material needs to be transported consistently. If the initial pass establishes a slot 3 metres wide, and the operator aims to maintain maximum efficiency, what should be the approximate width of subsequent passes within the established slot to prevent unnecessary spillage and ensure consistent material flow?

Answer options:

• 2 metres ✅ 3 metres
• 4 metres
• Initially 3 metres, then wider as the slot deepens

Correct answer: 3 metres

Explanation: To effectively use slot dozing, subsequent passes should maintain the established width of the slot. This ensures the sidewalls are consistently utilized to contain the material, preventing spillage and maximizing the volume moved per pass, as detailed in HEO operational best practices.
