sample, what is the (a) percentage of gravel,
(b) percentage of sand, (c)percentage of fines,
and (d) the USCS classification?
Q5. For a certain soil sample, assume that 60 percent
of the material passes the No. 200 sieve, that
there is no indication that the material contains
organic matter and that Atterberg limits testing
has been performed Figure 16-11 is the partially
completed record entries for the Atterberg limits
determination. Based on this information and
using the plasticity chart shown in figure 16-3,
what is the (a) liquid limit, (b) plasticity index,
and (c) USCS classification of the soil sample?
Q6. Which of the following field tests can be used to
approximate the cohesive and plastic
characteristics of a soil sample?
1. Dry strength
2. Ribbon
3. Roll
4. Each of the above
