In geotechnical engineering soil compaction plays an important role in ensuring the stability and durability of construction projects because this component is the base for the whole construction project. If this is weak, the entire project may collapse. Proctor Compaction Test is a fundamental laboratory test that determines the optimal moisture content at which soil will reach its maximum dry density. Based on the results of this test, engineers design the earthworks for foundations, embankments and roadways etc.
Proctor Compaction Test is developed by R.R. Proctor in 1933 to measure the relationship between the moisture content of soil and its dry density. The aim is to find the optimum moisture content (OMC) and maximum dry density (MDD) for a given soil type. There are two common types of Proctor tests: Standard Proctor Test (ASTM D698) and Modified Proctor Test (ASTM D1557).
Proctor Compaction Test is an essential soil test in civil engineering projects . Understanding and achieving the right soil compaction ensures the safety, durability and efficiency of all types of construction works. Therefore, it is necessary to determine the OMC and MDD before starting any project.
