The maximum dry density for Curve B is
93.2 pcf
The optimum moisture content for Curve A is
15.0%
Curve A represents
Modified Proctor compaction energy
For a standard Proctor compaction test, a 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?
104.4 pcf
What type of field compactor provides the best results in compacting sands?
A vibratory roller
Standard and Modified Proctor compaction tests were conducted on a soil.
What is the relationship between the maximum dry density and optimum
moisture content results for the two tests?
Ydmax is highter and Wopt is lower for the modified test than for the standard test
In a flow net:
Flow lines are perpendicular to equipotential (drop) lines
Given the flow net in figure 1 attached. There are how many flow channels in
the flow net?
