If the plastic limit is PL = 13.4% a. Draw the flow curve and obtain
the liquid limit.
b. What is the plasticity index of the soil? c.
Determine the liquidity index of the soil if Win situ = 32%
Q6: A saturated soil used to determine the shrinkage limit has initial
volume Vi= 20.2 cm3, final volume Vf = 14.3 cm3, the mass of
wet soil M1 = 34 g, and mass of dry soil M2 = 24 g. Determine the
shrinkage limit and the shrinkage ratio.
Q7: For a given sandy soil, the maximum and minimum void ratios
are 0.72 and 0.46, respectively. If Gs = 2.68 and
the moist unit weight of compaction
= 11%, what is
(kN/m3) in the field if Dr =
82%?
