Toughness Index: Toughness index is defined as the ratio of plasticity index (IP) of the soil to the flow index (IF) of the soil.
The toughness index varies between 0 to 3.
Calculation
Given
Liquid Limit = 25%, plastic Limit = 15 %, Flow index = 12 %
Plasticity Index = 25 - 15 = 10 % = 0.1
\(\begin{array}{l} Toughess\;index = \frac{{Plasticity\;index}}{{Flow\;index}}\\ \end{array}\)
Toughness index = 0.1/0.12
Toughness index = 0.833 = 83.33%
