Observed maximum densities and associated moisture contents of limestone blends resulting from standard and increased Proctor type compaction efforts. Porosities are calculated for each density
| Stone to soil ratio | Observed maximum dry density from 592.7 kJ/m3 effort | Observed optimum moisture content±1% | Porosity at optimum density from 592.7 kJ/m3 effort | Observed maximum dry density from 1609 kJ/m3 effort | Observed optimum moisture content | Porosity at optimum density from kJ/m3 effort |
