Multiple Choice

A lack of care during coring may cause core density to decrease.

Core density reflects how tightly the pavement was compacted, and the core must faithfully represent the in-place density. If coring is done without care, the sample can be damaged or contaminated, creating extra air voids or altering the core’s geometry. A rough cut, a crushed core, or rough handling at the ends can introduce voids or change the measured volume, causing the density calculation (mass divided by volume) to come out lower than the true in-place density. Therefore, lack of careful handling during coring can indeed reduce the measured core density. Proper technique—smooth cutting with the right equipment, cleaning ends, and gentle handling—helps ensure the core reflects the actual density.
