If the wet density of soil is 2,200 kg/m3 and the maximum dry density is 1,960 kg/m3, what is the degree of compaction?

To determine the degree of compaction, you need to compute the ratio of the wet density of the soil to the maximum dry density, then express it as a percentage.

Firstly, the maximum dry density is crucial in defining how dense the soil can get when fully compacted without any moisture. The wet density you have reflects the actual density of the soil in its current state.

The degree of compaction can be calculated using the formula:

[ \text{Degree of Compaction} = \left( \frac{\text{Wet Density}}{\text{Maximum Dry Density}} \right) \times 100 ]

Substituting the provided values into the formula:

[

\text{Degree of Compaction} = \left( \frac{2200 , \text{kg/m}^3}{1960 , \text{kg/m}^3} \right) \times 100

= 1.12244898 \times 100 \approx 112.25%

]

It seems you've indicated option C as the choice, which shows a degree of 101.23%. Based on the provided values, the calculated degree of compaction appears to be greater than 100%, suggesting that the wet
