The Proctor Test is a laboratory compaction test that determines a soil's maximum dry density and optimum moisture content by compacting samples at varying water contents. Its results provide the reference density against which field compaction is judged, and in data-center earthworks it underpins quality control of fill placement to ensure stable, low-settlement ground for foundations and slabs.
