Question: you are given a sample of soil with a dry...

Question details

You are given a sample of soil with a dry mass of 640 grams. This sample is washed prior to sieving. After washing, the dry mass of the soil sample is 568 grams. This washed material is then sieved using the stack of sieves listed in the table below. The table also shows the mass retained on each sieve after sieving is complete. Use the given data to prepare a grain size distribution curve. The curve should be plotted (using available software) on a semi-log graph showing percent passing as a function of particle diameter. Show all necessary calculations. Please take some time preparing and formatting your graph; a portion of your quiz score will be based on data presentation. Use your grain size distribution curve to classify the soil according to ASTM standards. Your classification must include both a Group Symbol and a Group Name. Note that Atterberg limits tests were performed on the fine-grained portion of this soil. The results were as follows: LL-33 and PL-24. Show all work to receive full credit.
