Atterberg Limits
1. The liquid limit (LL), plastic limit (PL) and shrinkage limit (SL) of a cohesive soil satisfy which of the following relations?
2. What happens to the volume of a soil sample as it is dried below its shrinkage limit?
3. The 'A-line' on the plasticity chart separates:
4. A soil with a plasticity index of 0 is considered:
5. The flow index (If) is determined from which laboratory test?
6. Which index provides an indication of the shear strength of soil at the plastic limit?
7. The atterberg limits of a clay are: LL = 60%, PL = 45% and SL = 25%. The natural moisture content is 50%. What is its state of consistency in nature?
8. A soil sample has a liquid limit of 40% and lies on the A-line. What is its plasticity index?
9. If the liquidity index of a soil is negative (IL < 0), the soil is in which state?
