If performed improperly, settlement of the soil could occur and result in unnecessary maintenance costs or structure failure.

Soil compaction - Wikipedia

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.

What is compaction test of soil? | AnswersDrive

The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density. This process is then repeated for various moisture contents and the dry densities are determined for each.
