Nov 01, 2007· From a Japanese standard compaction test which had a dynamic compaction energy of 551.3 kN m/m 3 due to an impact rammer of 2.5 kg falling into a mold of 1000 cm 3, a maximum dry density of 1.88 g/cm 3 was obtained at an optimum moisture content of 12.8%, corresponding to a degree of saturation of 82.1%.

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha).

Place Density to the Maximum Density. The degree of compaction, expressed as a percent, is then compared to the specification requirement to determine pass or fail. Maximum Density is a standard expressed in pounds per cubic foot which is arrived at by applying a standard compactive effort to a soil mixture under controlled conditions. 6 ...

Conclusion In conclusion, the bulk density of the coarse aggregates is determined. The bulk density for loose is 2232.2 kg/m3 while for compacted is 2506.0kg/m3. This results are correct as for loose bulk density it has lower weight due to presence of more pore spaces between the aggregates which results in low bulk density value.
