3/4 Clear Stone Compaction. Proctor compaction test is used to determine the optimal moisture content that a soil or aggregate will become densest. Aggregates with fines will need to achieve a minimum of 98% Proctor values to achieve proper compaction. However, with ASTM #57 stone you are unable to test using this.
