WebWhere: y Dr =50% is the dry unit weight at 50% relative density, yD r =70% is the dry unit weight at 70% relative density and Y d 1 pt is the field air-dry unit weight measured in kN/m 3 by compacting air-dry sand in a standard Proctor mould having a volume of 944 cm 3, using three lifts, with a 2.5 kg hammer dropped 305 mm for 25 blows per lift. WebAug 12, 2015 · Solving this for the maximum value of dry density results in $1919.67 \frac {kg}{m^3}$ at $12.57 \%$ moisture content. Note that you have a measured point that is above your interpolated maximum. This means you could either measure more points (to reduce uncertainty), choose a different fit, etc. But that is the general idea.
