Two methods are used for determining ___: Method A (multipoint) or Method B (one-point). -
ANSWER 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 ____. -
ANSWER A
The LL, PL, and PI are performed on the portion of the soil that passes the ____ sieve. -
