The width of carriageway recommended by IRC for a two-lane road without raised kerb Is:
Question 2
As per IRC, Recommended shape of transition curve is
Question 3
Calculate the maximum permissible speed on a horizontal curve of radius 125 m of a highway, designed for a speed of 65 kmph, if the superelevation is restricted to 7%. Take the permissible value of the friction coefficient as 0.15
Question 4
Calculate the extra widening of pavement needed on a two lane highway having a longitudinal circular curve of radius 300 m. design speed = 80 kmph, length of wheel base of largest vehicle = 6 m.
Question 5
The radius of a horizontal curve is 80 m. the design speed is 45 kmph. If super-elevation on curve is zero then coefficient of friction will be-
Question 6
Extra Widening of Pavement on a horizontal curve is provided to:
(i) Counteract the effect of off tracking
(ii) Increase visibility at curves
(iii) Maintain greater clearance between the vehicles
(iv) Provide aesthetic appearance on curves
Question 7
Consider the following statements:
Statement 1:It is necessary to provide set back distance on the inner side of horizontal curve.
Statement 2:Set back distance is the distance required from the centerline of a horizontal curve to an obstruction on the inner side of the curve to provide adequate sight distance at a horizontal curve.
Question 8
Consider the following statements:
(i) Superelevation is limited to a maximum value to avoid overturning of slow-moving vehicle.
(ii) Maximum limit of superelevation on a hill road not bound by snow is 8%
Which of the above statements are correct?
Question 9
The extra-widening of pavement because of psychological reasons is given by
Question 10
