Soil MechanicsProctor NeedleMEDIUM
Choose the correct answer
A
Shear strength in the field
B
Soil bearing capacity
C
Penetration resistance to estimate moisture content at a given density
D
In-situ CBR value
Correct Answer
C. Penetration resistance to estimate moisture content at a given density
Why is this the answer?
The Proctor penetration needle (IS 2720 Part 4) is a field device to determine the water content corresponding to a particular degree of compaction achieved in the field, by correlation with the laboratory Proctor test penetration resistance.
