For a given soil and compactive effort, the maximum dry unit weight is obtained at the:
Correct answer: D. Optimum moisture content
- A. Shrinkage limit
- B. Liquid limit
- C. Saturation moisture content
- D. Optimum moisture content
Explanation
The optimum moisture content is the water content at which a specified compactive effort produces maximum dry unit weight. Below or above this moisture content, the achieved dry density is lower.

About Soil Mechanics and Foundations
Soil mechanics examines index properties, phase relationships, classification, permeability, seepage, compaction, consolidation, shear strength and earth pressure. Foundations apply these principles to bearing capacity, settlement and shallow or deep foundation selection, with clear distinction between compaction, which expels air, and consolidation, which expels water over time.
