A Field Density Test assesses which property?

• A. A test for moisture in the air
• B. Concrete strength
• C. Structural steel yield
• D. Soil compaction density to meet project specs for bearing capacity and stability

Answer: (D)

Field Density Test measures how tightly the soil is packed in place. It determines the in-situ dry density and moisture content so you can verify that the compaction meets the project specifications. This directly relates to bearing capacity and stability, since properly compacted soil distributes loads and resists settlement. If the density is lower than specified, additional compaction is needed before proceeding with pavements, foundations, or fill sections. The other options refer to moisture in the air, concrete strength, or steel yield, which are not what a field density test assesses.
