05: The Figure below represents the data that was obtained from a liquid-limit test on
a soil. 50 percent of its particles is passing sieve #200. Two determinations for the
plastic limit gave water contents of 20.3 % and 20.8 %. Determine
1- Liquid Limit (LL).
2- Plasticity index.
3- Liquidity index if the water content is 27.4%
4- Void ratio at the liquid limit, if G, 2.7
5- Classify the soil based on AASHTO system.
