Challenge Problems
Push your limits with advanced challenges
A soil sample has an unconfined compression strength of 40 psi. After stabilizing with quick lime, the strength increases to 70 psi. Is this adequate for construction purposes? Explain your answer.
💡 Hint: Compare the initial and final strength with the required gains.
Given a soil stabilized with 4% cement, if the soil originally had a strength of 20 psi, calculate the new strength required for adequate stabilization.
💡 Hint: Add the necessary strength gain to the original strength.
