WitrynaThe shrink swell test is a simplified procedure developed to determine the shrinking and swelling properties of the soil without the need to measure soil suction. The test combines the measured soil shrinkage and swelling strains to produce an index value. WitrynaThere 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 the determination of Atterberg limits is relatively simple, it is more difficult to determine compressibility, permeability, and strength. great wolf lodge deposit
