Compaction is a process that increases the bulk density of soil or aggregates by removing air and optimizing moisture content to achieve maximum density. Understanding the relation between moisture content and density is crucial, as it influences soil strength, load-bearing capacity, and stability while reducing permeability and erosion damage. Key parameters such as Optimum Moisture Content (OMC) and Maximum Dry Density (MDD) are essential in the compaction process.
