Soil compaction is a key technique widely used in pavement and embankment construction. It is crucial to increase soil density and mechanical stability, enhance soil load-bearing capacity, and reduce the void ratio. This chapter delves into soil compaction, beginning with its basic premise as a mechanical method to enhance soil density by decreasing the air voids among soil particles, thus reinforcing the soil structure. The discourse differentiates between static and dynamic compaction, tailored for various soil types and project demands, where static compaction employs gradual pressure, and dynamic compaction involves vigorous impacts or vibrations. The efficacy of these methods is influenced by critical factors, such as soil moisture content and soil type (clay, silt, or sand), which dictate the compaction approach. The analysis extends to factors that impact compaction, highlighting the roles of soil texture, moisture, compaction energy, and equipment in achieving the desired compaction results. The discussion progresses to compaction control mechanisms, underscoring the need for real-time monitoring and adjustments to meet compaction goals while preventing soil overcompaction and damage. By providing an exhaustive understanding of soil compaction, this chapter aims to serve as an invaluable guide, shedding light on its practices, influences, and management strategies to optimize compaction in construction.
