87.

The maximum water content of a saturated soil at which a reduction in its moisture does not cause a decrease in volume of the soil, is called

A.	liquid limit	B.	plastic limit
C.	elastic limit	D.	shrinkage limit

88.

When water content in a soil is reduced beyond the shrinkage limit, the soil will be in a

90.

The plastic limit of a soil is defined as the

A.	limit of water that makes the soil to flow	B.	amount of water content which makes the soil to go into the liquid state
C.	amount of water content which makes the soil to go into the solid state from the liquid state	D.	minimum amount of water content which makes the soil to be rolled into 3 mm diameter threads
