Multiple Choice

A minimum of what QC density in any LOT should be obtained?

Explanation:
The density standard used for quality control is tied to the Standard Proctor test’s maximum dry density. In each lot, the compacted material should reach at least that maximum density to ensure the soil is packed tightly enough to minimize settlement, reduce water intrusion, and support loads. This makes the target explicit: achieve 100% of the Standard Proctor maximum density. Exceeding that value isn’t the goal or typically feasible in practice, and lower values indicate under-compaction that could compromise performance. The other options aren’t appropriate because they either set a lower threshold or imply a density beyond the established maximum.
