The one curiosity is the multiple-line chart shown in Figure H: The zero values, which are now #N/A error values, are clearly visible. This results in higher maximum soil densities at lower optimum moisture contents. It doesn't look like you need a secondary horizontal axis in this case so you can turn it on, set its crossing point to 0, and then hide the labels and tick marks. In-place measured densities of the compacted fill are compared to the Proctor test results to determine the degree of soil density. When you dont want to display zero values, you have a few choices for how to hide or otherwise manage those zeros. Explains the plasticity index, which measures the amount of water that must be added to change a soil from plastic limit to liquid limit. by . Water is added incrementally and mixed thoroughly to increase the individual moisture contents for each specimen by about 2%. Test procedures are similar, but the laboratory compactive effort of the modified method is higher. I have found this helpful is validating some curves. Already a Member? Since S = 1 when the saturation is equal to 100 percent, the relationship: Gsw=e can be substituted into the above equation (7.6) to yield the final equation for the ZAV line: All the wet points should fall on this line.
