Solution:
QUESTION: 14

According to Atterberg, the soil is said to be of medium plasticity if the plasticity index (PI) is:

Solution:
QUESTION: 15

A soil has liquid limit 65%, plastic limit of 30% and shrinkage limit of 25%, and it has natural moisture content of 45%. The liquidity index of soil is.

Solution:

Liquidity index = (water content-plastic limit)/(liquid limit-plastic limit).
= (45-30)/(65-30)
= 15/35
= 0.43
