Is there a Table/Chart to classify clay on whether they are expansive soil based on Plasticity Index?

Question

Atterberg Limit
Classification through the Degree of the Expansion of the clay soil which based on Plasticity Index

Plasticity Index (PI) = LL - PL

Answer 1

Atterberg Limit Tests are the most popular procedure for gathering information on the expansive
nature and mechanical behavior of clay soils. Atterberg limit tests measures the Liquid Limit
(LL) and Plasticity Index (PI) of the soils. Generally a PI of less than 25 is considered to denote
a low expansive potential of the soil, whereas a PI greater than 35 indicates a high expansive
potential of the soil. Similarly a value less than 50 for LL indicates a low expansion potential
and a value greater than 60 for LL indicates a high expansion potential.
