GEOTECHNICAL ENGINEERING A soil sample is oven-dried from its liquid limit state to its dry state causing a volume change of 19.68% of the dry volume. Likewise, the same soil is oven-dried from its plastic limit state to its dry state causing a volume change of 8% of the dry volume. The liquid limit and plastic limit are 60.54% and 50.37%, respectively. Determine the specific gravity of soil solids, shrinkage limit and shrinkage ratio.
Is it possible for a soil to have a liquid limit and a plasticity index(PI) both equal to 30%?Why?

How is the plasticity index of a soil determined?
The properties of seven different clayey soils are shown below (Skempton and Northey, 1952). Investigate the relationship between the strength and plasticity characteristics by performing the following tasks: a. Estimate the plasticity index for each soil using Skemptons definition of activity [Eq. (4.28)]. b. Estimate the probable mineral composition of the clay soils based on PI and A (use Table 4.3) c. Sensitivity (St) refers to the loss of strength when the soil is remolded or disturbed. It is defined as the ratio of the undisturbed strength (f-undisturbed) to the remolded strength (f-remolded)) at the same moisture content [Eq. (12.49)]. From the given data, estimate f-remolded for the clay soils. d. Plot the variations of undisturbed and remolded shear strengths with the activity, A, and explain the observed behavior.
2. A sample of soil has 60% passing the No. 4 sieve and 42% passing the No. 200 sieve. The liquid limit (LL) for the soil is 28%, and the plasticity index (PI) is 4.5%. Classify this soil according to the USCS.
