2.

The minimum value of camber provided for thin bituminous surface hill roads, is

 [A]. 2.2% [B]. 2.5% [C]. 3.0% [D]. 3.5%

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.

 Shahid Firoz Malik said: (Feb 5, 2021) Acc to IRC, it is necessary to drain off water from road hence more slope is provided. 2.5%.
