Question

Do the following:

a) Calculate the percent retained and percent passing each sieve, and graph the results on a semi-log graph (you may use the attached chart, or graph in Excel and include with your submission). Then, characterize the gradation of the material.

b) Calculate the values of D10, D30, D60, Cu, and Cc 

c) If the LL is 48 and the PL is 26, determine the USCS classification of the soil, and state its suitability for the purpose stated in the scenario. 

A sieve analysis was performed on a sample of the top layer of the soil, with the results shown
