CORRECT
A colluvial soil is a soil which was formed by: - (ANSWER)deposition of soil particles at the base of a
slope by gravity
For the particle size distribution shown above which of the soils is the best example of a well-graded
soil? - (ANSWER)Soil C
For the particle size distribution shown above, which soil is most likely to represent a silty sand (SM)
according to the USCS? - (ANSWER)Soil A
A sample of clay soil for testing in the triaxial compression test can best be sampled with a: -
(ANSWER)Shelby tube sampler
Given a soil that has a moist unit weight of 122.8 pcf, wc is 26.4 %, and Gs = 2.71. The dry unit weight for
the soil is most closely represented by: - (ANSWER)97 lb/ft3
A moist soil sample weighing 5 lb has a moisture content of 2%. How many mL of water must be added
to the sample to increase the moisture content to 10%? - (ANSWER)0.39 lb of water
A compacted fill, currently under construction, will 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, -
(ANSWER)103%>90% Do not meet the specs
What type of field compactor provides the best results in compacting sands - (ANSWER)a vibratory roller
Consider the permeameter shown below with the 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 - (ANSWER)3.5 x 10-1 cm/sec
