Question: When constructing a temporary access road on a soft, cohesive soil, which bucket-loading technique is most efficient for a wheel loader to achieve optimal fill material compaction?
Answer options:
- V-loading, then spreading the material in thick lifts (layers). ✅ Straight-approach loading, then spreading in multiple thin lifts by 'dozing' with the bucket.
- Load-and-carry, then dumping quickly in large piles.
- Cross-pile loading, then spreading material in a single, high lift.
Correct answer: Straight-approach loading, then spreading in multiple thin lifts by 'dozing' with the bucket.
Explanation: For effective compaction of fills, material should be spread in thin, uniform lifts. A straight-approach or 'dozing' technique with the bucket allows for precise placement and spreading in thin layers, which then facilitates better compaction by subsequent passes of the loader tires or dedicated compaction equipment.
