2. Plot the grain size distribution curves for the following soils and for each report: a) \( D_{10} \), b) \( D_{30} \), c) \( D_{60} \), d) coefficient of uniformity \( C_{u} \), e) coefficient of curvature \( C_{c} \) and f) percent gravel, sand and fines (clay \( + \) silt). Plot all three curves on the same figure of Percent passing by mass (\%) versus Grain diameter \( (\mathrm{mm}) \) - see example in Figure 2.6. Make \( x \) axis log scale, use symbols to represent the measured data, and use USCS definitions for \( \% \) gravel, sand and fines.
GRADATION CURVE It is used to represent particle size on x-axis and percentage finer on y-axis. X-axis is a log scale. COEFFICENT OF UNIFORMITY Cu = COEFFICIENT OF C
