Core samples should be protected from jarring during transport.

• A. True
• B. Not Stated
• C. Not Applicable
• D. False

Answer: (A)

Core samples must be kept intact to ensure test results reflect the actual pavement material. Jarring or rough handling during transport can cause cracks, breakage, or movement of the core within its sleeve, which alters its dimensions, density, and the distribution of binder and aggregates. This damage or disturbance can lead to inaccurate measurements and non-representative results. Using sturdy, purpose-built containers with cushioning and securing methods keeps the core from shifting and breaking, preserving orientation and condition for reliable testing. So the statement is true because protecting core samples from jarring safeguards their integrity and the validity of subsequent analyses.
