Referring to the attached grain size plots, carefully read the appropriate grain size values from the bottom of the graph and for each of the curves (2 & 3 only), plot them in a table and then determine Cu and Cc for each distribution. Could you please explain how to read the plot and find the grain size value :) Thanks

Soil engineering for highway design

Soil engineering is a part of geotechnical engineering that deals with the characteristics of soil. It also helps to understand the behavior of the soil in different conditions. The basic concepts of soil are studied to check the strength, compressibility, and porosity of the soil. This makes soil engineering an important topic for civil engineering.
