Which statement describes the maximum density determination sheet?

• A. A narrative summary
• B. A standard field log
• C. A data sheet for compaction tests
• D. Different materials with lab proctors (maximum density)

Answer: (D)

This is a lab data sheet used to record maximum dry density determinations for different materials during Proctor-type compaction tests, overseen by lab personnel. It captures the results of testing how much density you can achieve at various moisture contents for each material, identifies the highest density (the maximum density) and its corresponding moisture content, and then serves as the official record to establish compaction requirements for each material. The other options don’t fit because a narrative summary or a field log doesn’t document these lab-derived density values, and a general data sheet for compaction tests is too broad—it doesn’t specifically capture the systematic determination of maximum density across multiple materials under lab supervision.
