Determination of adequate compaction is done by determining the in-situ density of the soil and comparing it to the maximum density determined by a laboratory test. The most commonly used laboratory test is called the Proctor compaction test and there are two different methods in obtaining the maximum density.
Determining optimal compaction involves measuring the in-situ density of soil and comparing it to the maximum density determined by a laboratory test, specifically using the Proctor compaction test. There are two distinct methods for determining the maximum density.
