authority and if no method is specified, us the ___ method. - ✔✔Wet
|| || || || || || || || || || || ||
Two methods are used for determining ___: Method A (multipoint) or Method B (one-
|| || || || || || || || || || || || ||
point). - ✔✔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 ____.
|| || || || || || || || || || || || || || || ||
- ✔✔A||
, The LL, PL, and PI are performed on the portion of the soil that passes the ____ sieve. -
|| || || || || || || || || || || || || || || || || || ||
✔✔No. 40 ||
The water content, in percent, of the soil at the arbitrarily defined boundary between liquid
|| || || || || || || || || || || || || || ||
and plastic states is known as the ___. - ✔✔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 ___. - ✔✔Plastic Limit (PL)
|| || || || || || || || ||
The ___ is calculated as the difference between the liquid limit and the plastic limit. The
|| || || || || || || || || || || || || || || ||
equation is as follows: || || || ||
___ = __ - ___. - ✔✔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 ____. - ✔✔Atterberg limits
|| || || || || || || || || || || ||
The Plastic Limit "hand method" requires placing a mass of soil on a glass plate, then - with
|| || || || || || || || || || || || || || || || || ||
your fingers - roll it into a ___ in diameter. - ✔✔1/8 inch
|| || || || || || || || || || || ||
When sampling from a roadway, obtain at least ___ equal increments selected randomly
|| || || || || || || || || || || || ||
from the unit being sampled. - ✔✔3
|| || || || || ||
If sampling from a stockpile of fine aggregate, always remove the ___ and sample the
|| || || || || || || || || || || || || || ||
material beneath. - ✔✔Outer layer || || || ||
The Standard Effort lab max applies to soils that have 30% or less by weight retained on the
|| || || || || || || || || || || || || || || || || ||
___. - ✔✔3/4-inch sieve
|| || ||
