A liquid limit test conducted on a soil sample in a Casagrande cup device gave the following results:

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

Number of blows $1019232740$

Water content $(\%)60\mathrm{.}045\mathrm{.}239\mathrm{.}836\mathrm{.}525\mathrm{.}2$

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

Two determinations for plastic limit gave water contents of $20\mathrm{.}3\%$ and $20\mathrm{.}9\%.$ The natural water

content of the soil was determined to be $35\%.$ Determine: a$)$ the liquid limit and plastic limit; b$)$

the plasticity index; c$)$ the liquidity index; and d$)$ the void ratio at the liquid limit $($Assume a value

for Gs $).$ e$)$ If this soil $($at its insitu natural water content$)$ were to be loaded, what behaviour would

you expect $($brittle$,$ soft and yielding etc.$)?$ f$)$ Plot a plasticity chart and provide the USCS

classification.
