The degree of compaction achieved in the field is expressed in terms of relative compaction, which is defined as:
1
Relative compactions = \(\rm \frac{field \ dry \ density}{laboratory \ maximum \ dry \ density}\)
2
Relative compactions = field dry density × laboratory maximum dry density
3
Relative compactions =\(\rm \frac{laboratory \ maximum \ dry \ density}{field \ dry \ density}\)
4
Relative compactions = \(\rm \frac{1} {field \ dry \ density \ \times \ laboratory \ maximum \ dry \ density}\)
