Hydrometer readings shall be taken from the ___. - ANS Top of the meniscus
Two methods are used to prepare a test for liquid limit (LL), plastic limit (PL), and plasticity index

, Two methods are used for determining ___: Method A (multipoint) or Method B (one-point). -
ANS Liquid Limit (LL)
The method of preparation for the LL shall be specified by the requesting authority and if no
method is specified, there is a dispute, or greater precision is required, use Method ____. -
ANS A
The LL, PL, and PI are performed on the portion of the soil that passes the ____ sieve. -
ANS No. 40
The water content, in percent, of the soil at the arbitrarily defined boundary between liquid and
plastic states is known as the ___. - ANS Liquid Limit (LL)
The water content, in percent, of a soil at the boundary between the plastic and semi-solid
states is known as the ___. - ANS Plastic Limit (PL)
The ___ is calculated as the difference between the liquid limit and the plastic limit. The
equation is as follows:
___ = __ - ___. - ANS Plasticity index;
PI = LL - PL
Originally there were six "limits of consistency" of fine-grained soils. Now LL, PL, and in some
references, the shrinkage limit is known as the ____. - ANS Atterberg limits
