16. Factors affecting Compaction
The chapter discusses various factors affecting soil compaction, including water content, amount and method of compaction, soil type, and the addition of admixtures. It explains how these factors influence maximum dry density (MDD) and optimum moisture content (OMC), highlighting the relationship between water levels and density as well as the significance of different compaction methods and soil characteristics.

What we have learnt
- Compacted density initially increases with water content until an optimum level is reached, beyond which it decreases.
- The amount and method of compaction significantly influence the maximum dry density and optimum moisture content of the soil.
- Different soil types achieve varying densities based on their moisture content and compaction methods.
Key Concepts
- -- Maximum Dry Density (MDD)
- The highest density that a soil can achieve under specific compaction conditions.
- -- Optimum Moisture Content (OMC)
- The moisture content at which a soil reaches its maximum dry density during compaction.
- -- Compactive Effort
- The amount of energy applied during the compaction process, which affects the density and structure of soil.
