The optimum moisture for Curve A is: 15%
Curve A represents: Modified Proctor compaction energy
For a standard Proctor compaction test, a 104.4
sample was determined to have a total unit
weight of 118.0 pcf and a moisture content of
13%. What is the dry unit weight of this
sample?
The maximum dry density for curve B is: 93.2 pcf
What type of field compactor provides the A vibratory roller
best results in comparing sands?
Which of the following relationships is true ymax is higher and wopt is lower for the for the modified test
concerning the maximum dry density (ymax) than for the Standard test
and optimum moisture content (wopt) results
between standard Proctor and modified
Proctor test?
In flow net: Flow lines are perpendicular to equipotential (drop) line
1: What is the flow under the dam if the 1: 3.5
permeability (k) of the soil is 1.0 ft/day? 2: 1.3
2: What is the factor of safety against a quick
condition if ysat= 100 pcf
A sample of sand has a mass of 379.0 grams 12.46
after oven drying. Determine the natural
water content of this soil.
With reference to the soil profile shown, 1: 1248.6
answer the following questions. 2: 1250
1: What is the pore water pressure at Point 3: 1676
A?
2: What is the total stress at Point C?
3: What is the effective stress at point B?
If a consolidation test were conducted on a Cv
clay soil, which parameter from the test
results would be used to determine the time
rate of settlement?
One of the best methods for determining Cone penetration test
strength of soils when designing piles for a
deep foundation:
Using the soil profiles, what is the shear 60
strength of the soil at point B? yx= 9.81
