For water bound macadam roads in localities of heavy rainfall, the recommended value of camber is Correct Answer 1 in 36

For water-bound macadam roads in localities with heavy rainfall, the recommended value of camber is typically 1 in 36. Camber is the cross-sectional slope or curvature given to the road surface to ensure the proper drainage of rainwater.

In areas with heavy rainfall, it's essential to provide adequate camber to allow rainwater to drain off the road surface efficiently. The 1 in 36 camber means that for every 36 units of horizontal distance, the road surface rises by 1 unit vertically. This slope helps in preventing waterlogging and maintaining the road's integrity in heavy rainfall.

The other options (1 in 30, 1 in 48, and 1 in 60) may be used in different contexts or regions, but for localities with heavy rainfall, 1 in 36 is a common and suitable choice.

So, the correct answer is Option B: 1 in 36, which is the recommended camber value for water-bound macadam roads in areas with heavy rainfall.
