6 / 10

Central road fund was created in the year

7 / 10

The slope provided to road surface in the transverse direction to drain the rain water from road surface is called

8 / 10

A road 10 m wide is to deflect through and angle of 65° with the centreline radius 350 m. A transition curve is to be used at each end of a circular curve of such a length that the rate of gain of radial acceleration 0.4 m3/s, when speed is 60 km/h. Find the shift of the transition curve

9 / 10

Find minimum sight distance to avoid head on collision of two cars approaching at 90 km/h and 60 km/h. Given that, reaction time of driver t = 2.5 seconds, coefficient of longitude friction f = 0.7 and brake efficiency of 50% in either case.

10 / 10

The centrifugal ratio of a vehicle is 0.25, width of vehicle is 2.4 m, height of vehicle to its CG is 4.2 m, lateral friction is 0.15, assuming no super-elevation, then
