The Proctor Compaction Test is a common soil laboratory test that determines the moisture-density relationship of a soil sample, including its maximum dry density (MDD) and optimum moisture content (OMC). These results help establish proper soil compaction requirements for construction. Learn More about the Proctor Compaction Test
eFieldData’s Proctor report automatically calculates and displays the relationship between dry density and moisture content for Standard Proctor (ASTM D698 / AASHTO T 99) or Modified Proctor (ASTM D1557 / AASHTO T 180) test methods.
