During a compaction control test under NZS 4402, a fill sample is found to have a relative compaction of 92% of the Maximum Dry Density (MDD). If the project specifications require a minimum of 95% MDD, what directive should the land development engineer issue to the contractor?

Scarify, condition and re-compact the lift, then re-test it. Proceed with the next layer of fill, as a 3% variance is within standard field tolerance. Apply a cement stabilization agent to the surface and seal it immediately. Increase the thickness of the next lift to compensate for the lower density of the current layer.

Correct Answer:

Scarify, condition and re-compact the lift, then re-test it.
