The Standard Proctor Test is used in the laboratory to determine the optimum moisture content and maximum dry unit weight from a representative soil sample taken from the construction site. It is also known as the "MoistureDensity Relationship" Test or "Ordinary" Compaction and is suitable for particles no larger than 20mm.
