The major cross section elements considered in the design of streets and highways include the?
A. pavement surface type
B. cross slope
C. lane widths
D. All of the above
Explanation: The major cross section elements considered in the design of streets and highways include the pavement surface type, cross slope, lane widths, shoulders, roadside or border, curbs, sidewalks, driveways, and medians.
Pavement surface type is determined by?
A. soil volume
B. traffic condition
C. initial cost
D. All of the above
Explanation: Pavement surface type is determined by soil conditions, traffic volume, traffic composition, material availability, initial cost, and the extent and cost of maintenance
The high point of a normal cross slope of a roadway is known as the _______.
Explanation: The high point of a normal cross slope of a roadway is known as the crown.
The minimum cross slope for concrete pavement and hot mix asphalt pavement should be ?
Explanation: The minimum cross slope for concrete pavement and hot mix asphalt pavement should be 1.5 percent
Lane widths have a great influence on driving safety and comfort.
C. Can be true or false
D. Can not say
Explanation: Lane widths have a great influence on driving safety and comfort. The predominant lane width on freeways and land service highways is 12 feet.
The braking efficiency mainly depends on ___________
A. Sight distance
B. PIEV theory
D. Length of the curve
Explanation: The braking efficiency mainly depends on friction and speed of the vehicle, if the speed of vehicle is more, then braking efficiency will be less.
If the longitude coefficient of friction is 0.4, then the resultant retardation in m/sec^2 as per IRC will be ___________
Explanation: The deceleration of the vehicle mainly depends on the speed of the vehicle and coefficient of friction; however IRC has calculated the average value is 3.93 m/sec^2 from equations of motion.
If the camber is x%, then cross slope is ___________
Explanation: The cross slope is generally expressed in n in 100 terms, so the cross slope is X/100.
A median is also called as ___________
A. Traffic separator
B. Traffic junction
C. Traffic check post
D. Traffic flow
Explanation: The median may be a physical marking, divided area or protected by physical structure to avoid head on collisions.
The desirable width as per IRC for median on rural roads is ___________
A. 2 m
B. 3 m
C. 4 m
D. 5 m
Explanation: The desirable width is 5m on rural roads which can be reduced to 3m if there is a restriction of land.
