Websignificant components in the soil. Figure 3-2 is a flow chart for assigning typical names and group symbols for inorganic fine-grained soils; figure 3-3 is a flow chart for organic fine-grained soils; figure 3-4 is a flow chart for coarse-grained soils. Refer to tables 3-1 and 3-2 for the basic group names without modifiers. If The values of these limits are used in a number of ways. There is also a close relationship between the limits and properties of a soil such as compressibility, permeability, and strength. This is thought to be very useful because as limit determination is relatively simple, it is more difficult to determine these other properties. Thus the Atterberg limits are not only used to identify the soil's classification, but it allows for the use of empirical correlations for some other engineering prope…
