Previous question Next question Transcribed Image Text from this Question. Standard value of number of blows (N) = 25 (tolerance = 15). “Plastic soil” generally means the soil is predominantly clay – and the more plastic the soil, the more expansive it will likely be. A plasticity index (PI) of 15 or greater 2. More plastic soils can form longer worms. Their liquid limit and plastic limit are said to coincide because at … The plasticity chart has a shaded area; soils that plot in this area (above the A-line with PI values between 4 and 7) are silty clay and are given the dual symbol CL-ML.
