Where are all test data recorded?

• A. Lab notebook
• B. Field notebook
• C. Earthwork density report
• D. Temperature log

Answer: (C)

All test data for density tests are captured in the Earthwork Density Report. This official form is designed to collect the test results, location, date, operator, equipment used, moisture content, field density, and any acceptance criteria, creating a single, auditable record for QA/QC and project records. While lab notebooks and field notebooks may hold raw observations and notes, they are not the formal repository for all test data. A temperature log tracks ambient or material temperature for certain tests, but it does not replace the Earthwork Density Report as the primary record of density test data.
