Question

For water bound macadam roads in places of heavy rainfall, the recommended value of camber is ____

• A. 1 in 36
• B. 1 in 30
• C. 1 in 48
• D. 1 in 60

Hint:

Typical IRC camber values: \[ \boxed{ \begin{aligned} \text{Cement Concrete} &\approx 1:60\\ \text{Bituminous} &\approx 1:50\\ \text{WBM} &\approx 1:36 \end{aligned} } \]

Answer 1

The Correct Option is A

Step 1: Recall the purpose of camber. Camber is the transverse slope provided on the road surface to facilitate quick drainage of rainwater.

Step 2: Recall the IRC recommendation. For water bound macadam (WBM) roads in regions of heavy rainfall, the recommended camber is \[ \boxed{1 \text{ in } 36} \] Hence, \[ \boxed{(A)} \] is the correct answer.
