The main purpose of camber on a road is to:
Reduce vehicle speed
Drain off rainwater
Increase pavement friction
Improve roadway aesthetics
Which camber is preferred for cement concrete roads?
Straight camber
Parabolic camber
Combined camber
No camber
Carriageway width mainly depends on:
Traffic volume
Pavement type
Climatic conditions
Designer preference
Standard width of a single-lane road is:
3.0m
3.75m
4.25m
5.5m
The portion of a road used by vehicles is the:
Shoulder
Footpath
Carriageway
Median
A median is provided to:
Separate opposing traffic
Increase vehicle speeds
Reduce pavement thickness
Provide surface drainage
Raised medians are used in:
Rural roads
Urban roads
Mountain roads
Low-volume village roads
Superelevation is provided on:
Vertical curves
Horizontal curves
Straight reaches
Bridge decks only
Superelevation helps to:
Increase skidding
Reduce skidding
Improve drainage only
Reduce vehicle length
Superelevation is also called:
Camber
Banking
Gradient
Widening
Maximum superelevation in plain terrain is:
1:10
1:15
1:20
1:25
Gradient means:
Horizontal curvature
Vertical slope of road
Pavement thickness
Surface roughness
Ruling gradient is:
Steepest allowable gradient

Overtaking sight distance is for:
One-way streets
Two-lane roads
Multi-lane divided highways
Cul-de-sacs
Sight distance is measured along the:
Centre line
Curb line
Edge of shoulder
Median line
Standard reaction time is:
1.0s
2.0s
2.5s
3.5s
Horizontal curves are provided to:
Improve drainage
Change direction
Reduce speed permanently
Increase camber
The simplest horizontal curve is:
Transition (spiral)
Compound curve
Reverse curve
Simple circular curve
A transition curve is provided to:
Provide resting area
Introduce superelevation
Reduce pavement thickness
Prevent overtaking
Vertical curves are provided when:
Two gradients meet
The road crosses a river
Shoulders are narrow
Temperature fluctuates
Summit curves are called:
Sag curves
Crest curves
Reverse curves
Spiral curves
Valley curves are based on:
Sight distance only
Comfort
Drainage
Construction ease
Headlight sight distance is relevant for:
Summit curves
Valley curves
Horizontal curves
Tangents
A smooth change of gradient is achieved by a:
Superelevation
Vertical curve
Widening
Transition spiral
Road arboriculture means:
Cutting roadside trees
Plantation along roads
Design of medians
Roadside drainage
An advantage of roadside trees is:
Reduced pavement strength
Shade and aesthetics
Increased crash frequency
Reduced visibility at all times
Trees should not be planted at:
Along medians
Near bus bays
Sharp curves
On service roads only
Ideal tree spacing is:
3–4m
6–8m
10–12m
15–20m
A common highway tree is:
Bamboo
Neem

International Roads Council
Indian Roads Congress
Institute of Road Construction
Indian Roadways Commission
A shoulder is used for:
Long-term parking
Emergency stopping
Planting trees
Pedestrian movement only
Sight distance is measured from the:
Road centre
Driver’s eye
Tail lamp of the vehicle ahead
Median edge
