DETERMINATION OF COMPACTION FACTOR FOR SOIL

Compaction factor is defined as the ratio of Loose thickness divided by the designed thickness when the field trials are being conducted. For example, in case of embankment if the Maximum Dry Density value of the soil tested as per IS 2720 part 7 or 8 works out to be 1730 Kg/Cum. Its equivalent density at 95% compaction shall be 1643.5 Kg

Fundamentals of Soil Compaction

2021-2-19  • 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 liquefy during earthquakes. 3.2 Factors affecting Compaction
