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… WebInorganic clays, silty clays, sandy clays of low plasticity : CL: 27: 35 [1], Clays of low plasticity - compacted: CL : 28 [3 cited in 6] Organic silts and organic silty clays of low plasticity: OL: 22: 32 [1], Inorganic silts of high plasticity : MH: 23: 33 [1], Clayey silts - compacted: MH : 25 [3 cited in 6] Silts and clayey silts ...
