4. The result of a sieve analysis for a soil sample is given in Table 1. The soil does not exhibit any plastic behavior when water is added to it. a. Plot the grain size distribution curve. You should use either an engineering semi-log graph paper or any available software for this plot. Axes should be labeled properly. Plot without a proper scale will not be graded. (25 pts) Calculate C₂ and Cc. (10 pts) b. c. Following your answer in parts (a) and (b), comment on the gradation of the soil. (5 pts) d. Classify the soil based on AASHTO and USCS classification systems. Clearly mention the steps that you follow; points will be deducted otherwise.
