Question 1 (a) The grain size distribution data and of Soil A are as shown below. Sieve size 3/8 in % Passing 100 No. 4 87 No. 10 73 No. 40 47 No. 200 17 PL = 16, LL = 28 (1) Determine the Group Symbol and Group Name of the soil using USCS (show all steps clearly) (ii) The natural water content of the soil in the field is 13%. When sheared would this material behave in a brittle, plastic, or liquid manner? Show how you arrive at your conclusion For the laboratory test data given below, classify soils B & C according to the Unified Soil Classification System. (Show details of your procedure). Soil B: D10=0.2 mm D30 = 0.73 mm D60 = 1.27 mm % passing No. 4 = 77.5 % passing No. 200=4.0 Soil C: D10=0.3 mm D30=0.83 mm D60 1.37 mm % passing No. 4 = 92.5 % passing No. 200 = 20 LL-28 PL-15
