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.
Sections
Compaction is the process of increasing soil density by removing air, which enhances various soil properties.
Compaction increases the density and strength of soil.
The Optimum Moisture Content (OMC) is critical for achieving maximum density.
Water acts as a lubricant during compaction, affecting the soil's dry density.
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.
