4 cards from this section. Quick, good the night before a test.
What is a gradient?
Think about how you describe a hill or slope.
What is the purpose of minimum gradients?
Consider why water flows away from surfaces.
What does a ruling gradient indicate?
Consider which gradient helps vehicles the most.
True or False: Exceptional gradients can be used without any restrictions.
Think about safety and design limits.
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.
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.
Study the IRC specifications for different terrains when designing.
