Plasticity Index

Written by Jerry Ratzlaff on . Posted in Geotechnical

Plasticity index, abbreviated as PL, is scaling the natural moisture content of a soil sample in which soil remains in a plastic state while passing from a semisolid state to a liquid state.

 

formulas that use plasticity Index

\(\large{ PL =  LL - PL   }\)   

Where:

\(\large{ PL }\) = plastic limits

\(\large{ LI } \) = liquidity index

\(\large{ LL } \) = liquid limits
