Question: A sample of a brown sandy clay was obtained to determine its Atterberg limits and then classify its soil type according to the Unified Soil

A sample of a brown sandy clay was obtained to determine its Atterberg limits and then classify its soil type according to the Unified Soil Classification System. For one of the PL determinations, the wet + dish = 11.53 g and the dry weight + dish = 10.49 g. The dish only weighed 4.15 g. Compute the plastic limit. Another plastic limit was 16.9%. Three determinations of the liquid limit were made. For 17 blows, the water content was 49.8%; for 26 blows, the water content was 47.5%; and for 36 blows, the water content was 46.3%. Evaluate the soil type, indicate the information on a plasticity chart, and give the Unified Soil Classification symbol.
