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 The results of the particle-size analysis of the soil are as follows: Percent passing No. 10 sieve = 100; Percent passing No. 40 sieve = 80; Percent passing No. 10 sieve = 58. The LL and PI of minus No. 40 fraction of the soil are 30 and 10 respectively. Classify the soil by AASHTO system.Justify your answer. provide fbd a.A-6 (5) b.A-5 (6) c.A-4 (5) d.A-7-6 (20)

One of your junior engineers has submitted a construction quality (CQC) plan foryour review before it is sent to the client. The CQC plan includes a compactionspecification for the compacted clay liner. The specification requires that the clay becompacted to a dry unit weight 92% of maximum dry unit weight (standard Proctor)and wet of standard Proctor optimum water content. Compaction and hydraulicconductivity-water content curves for the soil are shown in the figure below. The clayliner is required to have hydraulic conductivity1 x 10-7cm/sec. Find the acceptablezone based on hydraulic conductivity. Does this specification ensure that the requiredhydraulic conductivity will be obtained? Part II: Explain the shape of the standard Proctor compaction and hydraulicconductivity-water content curves (above) in terms of the shear strength and fate of clodsduring compaction
