How to Use This Calculator
- Enter wet soil weight (lbs) and mold volume (ft³) from your Proctor test sample.
- Set measured moisture content (%) and soil specific gravity (Gs).
- Review Wet Density, Dry Density (pcf), Degree of Saturation (%), and Void Ratio.
- Compare dry density to the Proctor maximum to calculate compaction percentage.
