3 cards from this section. Quick, good the night before a test.
What are stabilizing agents?
Think about what we can add to soil to make it stronger.
How does densification affect soil density?
What happens to air spaces in soil during densification?
What is the primary effect of adding stabilizing agents to soil?
Think about what we aim to achieve with soil treatment.
Compacting soil dry of optimum typically produces what kind of structure?
Remember the effect of moisture on soil structure.
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.
Focus on the void ratio change and how it relates to density.
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.
Remember to consider load factors in your calculations.
