Cross slope in cross fall or camber which is provided for efficient drainage facilities and to improve drainage faculty of the ground.

For a setting up petrol pump you have to decide the road level and temporary benchmark after the known road level you have to give slope in such that water from the petrol pump can be easily drained away into the manhole by gravitational force and waterlogging does not occur for that you have to do a marks on the highest water logging level or flood level of the area by surveys of past 20 years flood level or waterlogging level so you can easily know the what should be the highest level of the embankment should be provided in the petrol pump area. In petrol pump, slope provided towards the road side and cross slope is provided.

Terrain : Cross slope of a country.

Plain : 0%-10%.

Rolling : 10%-25%.

Mountainous : 25%-60%.

Steep : >60%.

Thank you for explaining @Dileep.

Thanks @Dileep.

Yes, what is the exact percentage of cross Slope on hill roads? Please tell me.

What does exactly percentage cross slope of country? I mean it's physical significance?

1. What is cross slope of the country and how one can calulate it for setting up a petrolpump?

2. It is calculated on length or breadth basis?

3. The stretch of the road may be 50 km for calculating the slope of the country for setting up a petrol pump accoding to MORT&H?

Please send me the answers fast so that it may come in work. Thanks!
