Show Hint
On a straight road, we use Camber. On a curved road, we transition the Camber into Super-elevation. Both ensure water doesn't stay on the road!

- Both (A) and (R) are correct and (R) is the correct explanation of (A)
- Both (A) and (R) are correct but (R) is not the correct explanation of (A)
- (A) is correct but (R) is not correct
- (A) is not correct but (R) is correct

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
• Assertion: road camber helps in surface drainage. Reason: on a curved alignment, super elevation serves the purpose of camber.
Step 2: Detailed Explanation:
• (A) is correct: camber is the transverse slope that drains rainwater from the carriageway.
• (R) is correct: on a curve the super-elevation slope itself drains the surface, so separate camber is not provided.
• But (R) does not explain why camber helps in drainage; it only states what happens on curves.
Step 3: Final Answer:
The correct option is (B) Both (A) and (R) are correct but (R) is not the correct explanation of (A).
