Table of Atterberg limit results are shown in Appendix E. The liquid limit shown is 55 %, taken at the 20 mm penetration. I cannot use the option that hides all the zero values in that tab because there are other tables some cells have zero values and I need those zeros. You should be able to determine the percent saturation at the top of the curve and then determine whether this is abnormal or not. What role does moisture play? Any soil that is compacted will not be fully saturated - hence, as you are plotting dry unit weights, you must have air in many of the voids. The compaction curve theoretically does not cross this line but becomes parallel to it. Heres how: Theres no easy way to remove the zero in data labels. I have a big chunk of values (populated using equations), 1000 rows, and 4 columns. The saturation curve, or zero air voids curve, is a plot of soil density vs moisture at a theoretical 100% saturation level (zero air voids). Conclusion. The reader is encouraged to carefully read and understand the ASTM or AASHTO test methods.
