What does a liquidity index less than 0 signify?
Recall the classification ranges from the section.
What does a liquidity index greater than 1 indicate?
Think about the implications of a high water content in soil.
True or False: A liquidity index between 0.25 and 0.5 indicates stiff soil.
Recall the classification scale discussed.
If a soil has a plastic limit of 28%, liquid limit of 52%, and moisture content of 41%, calculate the liquidity index and classify it. What are the engineering implications?
Ensure to analyze how this impacts soil load-bearing capacity.
