Challenge Problems
Push your limits with advanced challenges
Evaluate a pavement design scenario with high moisture retention in the subgrade due to expansive soils. Suggest treatments and their rationale.
💡 Hint: Consider both chemical and physical methods for intervention.
In a case study, a highway constructed on high PI soils experienced cracking after heavy rains. How could the original design have integrated PI considerations?
💡 Hint: Look into pre-emptive design changes that ensure durability.
