Atterberg limits are a basic measure of the critical water contents of a fine-grained soil, such as its shrinkage limit, plastic limit, and liquid limit. The group performed standard practice in determining the liquid limit, plastic limit, and plasticity index of a soil sample in accordance to ASTM D 4318. The calculated liquid limit of the soil sample is 34, its plastic limit as 20, and plasticity index as 14. After analysis, the soil sample is recognized as clay of low plasticity based on the USCS.
