Challenge Problems
Push your limits with advanced challenges
Field measurements show that the in-situ dry density is 550 kg/m³, while the lab-determined MDD is at 600 kg/m³. Is the field density acceptable, and what actions would you recommend?
💡 Hint: Consider the percentages involved to guide your analysis.
The weight of the soil removed from an excavated hole is 8 kg, and it took 0.04 m³ of sand to fill the void. Calculate the in-situ dry density and assess if it meets an MDD of 700 kg/m³.
💡 Hint: Use the density formula you learned earlier.
