Compaction

Problem $4\mathrm{.}1$: A soil sample was compacted to achieve a maximum dry density of $1\mathrm{.}85\frac{g}{c}{m}^3$ at a

moisture content of $12\%.$ If the field density of the soil is $1\mathrm{.}70\frac{g}{c}{m}^3$ and the field moisture content is

$14\%,$ determine the degree of compaction achieved.

Solution Approach: Calculate the degree of compaction using the formula:

Degree of Compaction$(\%)=($Field Density$/$Maximum Dry Density$)100$

Also, compare the field moisture content with the optimum moisture content if needed.
