Question 1.
What is the purpose of the Standard Proctor test?
Show hintHide hint
Think about density measurement.
Question 2.
How much cement percentage is generally recommended for subgrade modification?
Show hintHide hint
Recall the specific range mentioned.
3Question 3.
What is the aim of the Standard Proctor test?
- To measure soil drainage
- To determine max dry density
- To assess soil fertility
Show hintHide hint
Consider what this test measures.
4Question 4.
The recommended cement percentage for subgrade modification is approximately 4%.
- True
- False
Show hintHide hint
Remember the specific percentage mentioned.
Question 5.
You are tasked with stabilizing a soil that has an initial compression strength of 75 psi. After applying 4% cement, a Standard Proctor test shows a maximum dry unit weight, but the unconfined compression test reveals only a 90 psi gain. What should your next steps be?
Show hintHide hint
Consider the implications of not reaching 100 psi.
Question 6.
A project requires a new subgrade to be laid with soil cement modified at 4.5%. Discuss the possible effects of using this percentage against the recommended range.
Show hintHide hint
Recall the specified acceptable range.
