[C]. 3.0%
[D]. 3.5%

Answer: Option B

Explanation:

No answer description available for this question.

Jaju Krishna said: (Jan 16, 2014)  
Because water is to drain out from camber frequently, hence more camber slope is provided.

Yogi said: (Mar 4, 2014)  
The minimum value of camber provided for high bituminous surface hill roads, is 2%.

Pawan Kumar said: (Mar 13, 2014)  
Range of camber for thin bitumen surface in hilly areas = 1 in 40 to 1 in 50.

Since it is hilly areas thus it should be 1in 40~2.5 percent.

Manoj Kumar Sah said: (Mar 31, 2014)  
Value of camber road for thin bituminous in urban area always 2.5 percent.

Devkate Govind said: (Jan 23, 2015)  
Type of road plain terrain hilly road.

1) For concrete & Thick bitumen road 2% 1.7%.

2) Thin bitumen 2.5 % 2%.

3) Wbm road 3% (3.3) 2.5%.

4) Earth road 4% 3%.

S.Harsha said: (Feb 27, 2015)  
Its exactly 2.5% because it is a bituminous hilly road.

Latifurrahman said: (Nov 12, 2015)  
2.5% to 3% that minimum value of camber.

Sourav Chakraborty said: (Aug 14, 2016)  
I think this questions is incomplete because camber is also depend upon area of amount of rainfall.

Ashu said: (Aug 22, 2016)  
According to IRC it is 2.5%.

Rahul said: (Aug 27, 2016)  
Please, Tell me about an Irc chart.

Nayak said: (Sep 2, 2016)  
The minimum value of camber 2.5%and 3%.

Sree Vidhya said: (Nov 11, 2016)  
It should be 2 to 2.5%.

Kalyan Rayudu said: (Nov 29, 2016)  
The minimum chamber provided for hill chamber is 2.5%.

Hashan Weragoda said: (Jan 3, 2017)  
Generally minimum chamber slope is 2%.

Siddhanth said: (Jan 5, 2017)  
cc, high bituminous - 2%.
Thin bituminous - 2.5%.
Wbm - 3%.
Earthen road - 4%.

Mohammad Salman said: (Jan 5, 2017)  
2.5% generally minimum camber in hill road.

Deshraj said: (Jan 13, 2017)  
In forest areas, why bitumen surface gets pach much with compare to normal areas?

Shahim said: (Feb 11, 2017)  
According to the AHC Specifications 2.5% is the correct answer.

Sourav said: (Mar 29, 2017)  
For Thin Bituminous, Min camber is 2% As per as IRC.

Chaitanya Raval said: (Mar 30, 2017)  
A tilt built into a road at a bend or curve, enabling vehicles to maintain speed.

Sharan said: (Apr 23, 2017)  
It depends on amount of rainfall also.

Sanjay said: (May 31, 2017)  
For thin bituminous road provide,

Heavy rain fall : 2.5%.
Normal rainfall : 2.0%.

Vishrut Saini said: (May 31, 2017)  
2.5% generally minimum camber in hill road.

King Maker said: (Jul 19, 2017)  
Thin bituminous surface 1÷40 = 0.025.
0.025 convert to %.
So 0.025*100 = 2.5%.

Rajesh said: (Aug 19, 2017)  
It is Depend on rain capacity.

Ayaz Ahmed said: (Aug 23, 2017)  
Generally 2.5% in hill areas.

Datta Wasmatkar said: (Sep 15, 2017)  
For bituman road 3% and wbm 4%.

Ali Gul said: (Oct 27, 2017)  
Exactly, 2.3 for hill road.

Anil said: (Nov 30, 2017)  
Thin bitumen 2.5.

Shivam Jaiswal said: (Dec 9, 2017)  
Generally, we provide 2.5% normal camber in the bituminous pavement and 3% in a concrete road.

Ayebare Junior said: (Dec 21, 2017)  
Generally, for thin bituminous pavements, the minimum camber should be 2.5% to cater for drainage of the surface runoffs.

Srimanta Haldar said: (Jan 26, 2018)  
In the hilly area where we can provide a minimum of 2.5% camber,& maximum of 10% camber.

Although 7% is max required for the road as per ISI. But in hill road, we can avoid as per position.

Kona said: (Apr 11, 2018)  
Hilly mean heavy rainfall area.

Ajay said: (Sep 25, 2018)  
For camber.

In CC road it is 1 in 50.
Thin bitumen 1 in 40.
Gravel 1 in 33.
Earthen 1 in 25.

Jeetendra said: (Jan 6, 2019)  
Camber for the thin bituminous surface.

In high rainfall - 2.5% or 1 in 40.
In light rainfall -2% or 1 in 40.

Aadarsh said: (Jan 8, 2019)  
Hill roads = Heavy Rainfall = 1in 40 = 2.5.

Abhishek K said: (Mar 17, 2019)  
CC/High Bituminous road - 1.7%(light rainfall), 2%(heavy rainfall).
Thin Bituminous road - 2%(light rainfall), 2.5(heavy rainfall).
WBM/gravel road - 2.5%(light rainfall), 3%(heavy rainfall).
Earthen raod - 3%(light rainfall), 4%(heavy rainfall).

K. Udaysree said: (Aug 22, 2019)  
Why we aren't providing crown for cement concrete roads? Please, anyone, tell me.

Sanket Dhamankar said: (Oct 31, 2019)  
Please, anyone, tell me what is the max limit of camber in hilly roads.

Avnish said: (Mar 9, 2020)  
If the crown is provided then there would be tension in upper and concrete are weak in tension, the crack will produce.

Samadhan Lendave said: (Apr 15, 2020)  
1) For concrete & Thick bitumen road 2% 1.7%.
2) Thin bitumen 2.5 % 2%.
3) Wbm road 3% (3.3) 2.5%.
4) Earth road 4% 3%.

Asmi said: (Sep 19, 2020)  
Type of Pavement : Heavy Rain fall --------------- Light Rain Fall
high type Bituminous surface &CC : 1 in 50 --------------- 1 in 60.
Thin Bituminous Surface : 1 in 40 --------------- 1 in 50.
WMM, Gravel : 1 in 33 --------------- 1 in 40.
Earth Road : 1 in 25 --------------- 1 in 33.
