• Compaction increases the shear strength of the soil. • Compaction reduces the voids ratio making it more difficult for water to flow through soil. This is important if the soil is being used to retain water such as would be required for an earth dam. • Compaction can prevent the build up of large water pressures that cause soil to
Compaction machine characteristics. Two factors are important in determining the type of force a compaction machine produces: frequency and amplitude. Frequency is the speed at which an eccentric shaft rotates or the machine jumps. Each compaction machine is designed to operate at an optimum frequency to supply the …

Compaction of calcareous sand and, even more, CPT testing of such sand causes crushing of the grains which influences the results. Evaluation of relative density of the compacted fill from CPT re-sistance by means of literature correlation formulas-cannot longer be applied as these formulas are valid for dry silica sand.
Subgrade compaction: Compact the exposed subgrade soil using the appropriate compaction equipment based on the soil type. Proper subgrade compaction is crucial, as it provides a stable foundation for the subsequent layers. Sub-base installation: Spread a layer of granular material, typically crushed stone, over the compacted subgrade.
