CE 360 Final Practice Exam Questions UPDATED ACTUAL QUESTIONS AND
CORRECT ANSWERS
A colluvial soil is a soil which was formed by: deposition of soil particles at the base of a slope by gravity
For the particle size distribution shown above which of Soil C
the soils is the best example of a well-graded soil?
For the particle size distribution shown above, which soil Soil A
is most likely to represent a silty sand (SM) according to
the USCS?
A sample of clay soil for testing in the triaxial Shelby tube sampler
compression test can best be sampled with a:
Given a soil that has a moist unit weight of 122.8 pcf, wc is 97 lb/ft3
26.4 %, and Gs = 2.71. The dry unit weight for the soil is
most closely represented by:
A moist soil sample weighing 5 lb has a moisture content 0.39 lb of water
of 2%. How many mL of water must be added to the
sample to increase the moisture content to 10%?
A compacted fill, currently under construction, will 103%>90% Do not meet the specs
support a proposed supermarket. One of the field
density tests in this fill gave a total unit weight of 121 lb/ft3
and a moisture content of 12.5%. A series of modified
Proctor tests have also on been performed on the fill soil
per ASTM D1557,
What type of field compactor provides the best results in a vibratory roller
compacting sands
Consider the permeameter shown below with the 3.5 x 10-1 cm/sec
following data:
Sample dia = 7.6 cm
Sample length = 15.2 cm
h = 38.5 cm
Q = 93 kg of water
t = 38 minutes
Determine: k in cm/sec
