Question: When backfilling a trench around a newly installed pipe, what is the primary reason for placing fill material in layers and compacting each layer?
Answer options: ✅ To prevent future settlement of the backfill material.
- To allow faster dewatering of adjacent soil.
- To reduce the amount of backfill material required.
- To increase the speed of the backfilling operation.
Correct answer: To prevent future settlement of the backfill material.
Explanation: Placing backfill material in layers and compacting each layer is crucial to prevent future settlement, which can lead to depressions in the surface, damage to the pipe, or structural instability. This method ensures uniform density and stability over time. It does not primarily affect dewatering, reduce material, or increase operational speed.
