Question

A soil sample was collected from a stack of materials prepared for a compaction site and a sieve analysis was performed to classify the soil. Shown in the table are the results of the sieve analysis.

Draw the grain size distribution curve (graph is given below) and show the D10, D30, D50and D60. According to USCS, please classify this soil. (b)A certain saturated sand (S = 100%) has a moisture content of 25.1% and a specific gravity of solids (Gs) of 2.68. It also has a maximum void ratio (emax) of 0.84 and a minimum void ratio (emin) of 0.33. Compute its relative density and classify its consistency.
