WebSince the proctor curve is based on dry density, each 2% moisture increase is the equivalent of approximately 30 grams for a proctor specimen. Thus if the last specimen is only 20 grams heavier than the previous (2% drier) point, this will show a reduced dry density. E. Calculations Example: Example: Wet Density = 1982 x 0.06614 = 131.1 pcf
