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

The laboratory test on a soil sample yields the following results:
natural moisture content - 18%, liquid limit = 60%
plastic limit = 25%,
percentage of clay sized fraction = 25%.
The liquidity index and activity (as per the expression proposed by skempton) of the soil,
respectively, are
