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… WebWIN: 25515.00 Project Name: Town: St George Stream Name: Route No. ME-73 Bridge Name: Asset ID: 46906 Analysis by: csh / mrl Lat: 44.01402 Long:-69.1852 Date: … graphic organizer ng kwento
