1.3. Accelerate the process of densification.

Try these first

1. 1.

   What are stabilizing agents?

   Hint

   Think about what we can add to soil to make it stronger.

2. 2.

   How does densification affect soil density?

   Hint

   What happens to air spaces in soil during densification?

3. 3.

   What is the primary effect of adding stabilizing agents to soil?

   • To reduce cost
   • To stabilize the soil
   • To increase water retention

   Hint

   Think about what we aim to achieve with soil treatment.

4. 4.

   Compacting soil dry of optimum typically produces what kind of structure?

   • True
   • False

   Hint

   Remember the effect of moisture on soil structure.

5. 5.

   Given a soil sample with initial void ratio of 0.6 and after compaction, the void ratio reduces to 0.4, determine the percent decrease in voids and the corresponding increase in density.

   Hint

   Focus on the void ratio change and how it relates to density.

6. 6.

   Calculate the potential increase in bearing capacity when a soil's density improves from 1.5 g/cm³ to 1.8 g/cm³. Assume a linear relationship for simplicity.

   Hint

   Remember to consider load factors in your calculations.
