Part 4 COMPACTION TESTING
Compaction tests results vary with the input compactive effort, usually measured in foot -pounds per cubic foot of soil. The line of optimum moisture contents is usually around 85% saturation and the optimum moisture content decreases with increasing compactive effort. Which Test Are You Using?

Proctor Compaction Test: A Basic Guide Gilson Co.
The Proctor Compaction Test establishes the maximum unit weight that a particular type of soil can be compacted to using a controlled compactive force at an optimum water content. This is the most common laboratory soil test and the basis for all engineered compacted soil placements for embankments, pavements, and structural fills.

Soil Density Testing: 3 Test Methods You Can Count On
This on-site compaction test is performed using the same type of mold, compaction hammer, and the number of blows as the original lab method. The moisture content is determined using a gas-pressure moisture tester or simple field dry-back methods. Density and moisture results are plotted against the original laboratory curve to confirm a match.
