Soil engineering for highway design

Soil engineering is a part of geotechnical engineering that deals with the characteristics of soil. It also helps to understand the behavior of the soil in different conditions. The basic concepts of soil are studied to check the strength, compressibility, and porosity of the soil. This makes soil engineering an important topic for civil engineering.

Question

If the liquid limit of soil is 25%, plastic limit is 15%
and flow index is 12.5%, then its toughness index
is:
1.
50%
2.
60%
3. 70%
4. 80%
