Part 4 COMPACTION TESTING - Missouri S&T

Most field compaction tests are now made using nuclear density gages that employ a cesium element. Nuc gages can have significant errors if the extendable probe is located next to a rock > 3 inches across. In rocky fills the operator should always rotate the probe 90 degrees and take a second reading, recoding the lower of the two values.
