The results of a particle distribution analysis for a sand is shown in Table Q2(a). Plot the particle size distribution curve on the chart provided at the end of the paper and determine the uniformity coefficient and the coefficient of curvature for the soil. Note: Ensure your student ID number is written on the chart and that the sheet is returned with your examination script. Mass retained Sieve size (mm) 10 (g) 0.0 6.3 5.5 2 25.7 1 23.1 0.6 22.0 0.3 17.3 0.15 12.7 0.063 6.9 Pan 2.3 Table Q2(a) Estimate the permeability of the sand and state why you believe the estimate to be reasonable. Explain when it is appropriate to conduct the Atterberg limit tests and discuss how these can be of value when selecting soil for the core of a dam. A soil has a plastic index of 40% and a plastic limit of 15%, determine its liquid limit and classify the soil using Casagrande's chart included in the aide memoire. What course of action is recommended when Atterberg limit results plot above the U-Line on Casagrande's chart?
