Challenge Problems
Push your limits with advanced challenges
Given a stretch of road requiring a ruling gradient of 4%, a limiting gradient of 5%, and an exceptional gradient for a steep hill of 7%, calculate the grade compensation required for a vehicle on a horizontal curve.
💡 Hint: Review how grade compensation works with different gradients.
Design a vertical alignment for a new highway section traversing varied terrain that includes low, moderate, and steep gradients. Identify required compensation and suggest suitable practices based on IRC standards.
💡 Hint: Study the IRC specifications for different terrains when designing.
