Answer 20

Liquid Limit

Question 21

moisture content at which the soil, when rolled to 1/8 inch (32.2mm) in diameter crumbles

Answer 21

Plastic Limit

Question 22

Soil mass shrinks as moisture is gradually, decreased or lost with continuous loss of moisture, a stage of equilibrium is reached at which more loss of moisture will result to no further volume change.

Answer 22

Shrinkage Limit
