What is the recommended range of camber for cement concrete roads in areas with heavy rainfall?
Answer: A
For cement concrete roads in areas with heavy rainfall, the recommended camber is 1 in 50, which is steeper than the 1 in 60 sometimes allowed in light rain. A cross-slope of this order drains the surface quickly, while a flatter one lets water stand. The values of 1 in 40, 1 in 33 and 1 in 25 are the cambers that are used for lower types of surface such as gravel, WBM and earth roads, which need a steeper slope because they are more permeable and rougher.
