Challenge Problems
Push your limits with advanced challenges
A civil engineer measures a soil's Atterberg Limits as: Liquid Limit = 40%, Plastic Limit = 25%. Calculate the Plasticity Index and discuss its implications for pavement design.
💡 Hint: Remember the formula for PI.
A soil undergoes a plate load test and settles under a load intensity of 100 kPa, causing a 5mm settlement. Calculate the k-value and discuss its importance in rigid pavement design.
💡 Hint: Consider what high and low k-values mean for pavement performance.
