Soil relative compaction calculator

Calculate relative compaction with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use relative compaction to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Relative compaction (%)

Field dry density/reference maximum dry density ×100; no acceptance criterion assumed.

Symbols and units

Field dry density (g/cm³)
b
Reference maximum dry density (g/cm³)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Field dry density/reference maximum dry density ×100; no acceptance criterion assumed. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
