Plot a graph of w against ln(d), and estimate the liquid limit w LL . If the soil has a plastic limit of 22%, calculate the plasticity index and classify the soil using the chart given in Figure 1.15. Q1.8 Solution The water content is the mass of water divided by the mass of soil solids, i.e. {(m s +m w +m t ) - (m s +m t )} {(m s +m t ) - (m t )}:...
