15. Compaction
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.

- Water acts as a lubricant during compaction, affecting the soil's dry density.
Key Concepts
- -- Compaction
- The process of increasing the bulk density of soil or aggregates by removing air.
- -- Optimum Moisture Content (OMC)
- The moisture content at which the maximum dry density of soil is achieved.
- -- Maximum Dry Density (MDD)
- The highest density that soil can achieve under a specific compactive effort.
- -- Air Voids
- The spaces within soil that are filled with air, affecting its density and traits.
