Highway Engineering (Set-1)

Nagpur road plan formulae were prepared by assuming

• Rectangular or block road pattern

• Radial or star and block road pattern

• Radial or star and circular road pattern

• Radial or star and grid road pattern

The Shape of the camber, best suited for cement concrete pavements,is

• Straight line

• Perabolic

• Elliptical

• Combination of straight and perabolic

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

• 1 in 30

• 1 in 36

• 1 in 48

• 1 in 60

When the path travelled along the road surface is more than the circumferential movement of the wheels due to rotation, then it results in

• Slipping

• Skidding

• Turning

• Revolving

The shoulder provided along the road edge should be

• Rougher than the traffic Lanes

• Smoother than the Traffic lanes

• Of same colour as that of the pavement

• Of very low load bearing capacity

On a single lane road with two way traffic, the minimum stopping sight distance is equal to

• Stopping distance

• two times the stopping distance

• Half the stopping distance

• Three times the stopping distance

The desire able length of overtaking zone as per IRC recommendation is equal to

• Overtaking sight distance

• Two times the overtaking sight distance

• Three times the overtaking sight distance

• Five times the overtaking sight distance

If the stopping distance is 60m then the minimum stopping sight distance for two lane, two way traffic is

• 30 m

• 60 m

• 120 m

• 180 m

The effect of grade on safe over taking sight distance is

• To increase it on descending grades and to decrease it on ascending grades

• To decrease it on descending grades and to increase it on ascending grades

• To increase it on both descending and ascending grades

• To decrease it on both descending and ascending grades

The terrain may be classified as rolling terrain if the cross slope of land is

• Up to 10 %

• Between 10 % and 25 %

• Between 25 % and 60 %

• More than 60 %
