Explain with neat sketch of cross section of road pavement in embankment showing different elements and write their functions.
- b)[6]
What is purpose of providing camber? Explain with sketches different shapes of cross slopes of road pavement?
- c)[6]
Calculate minimum sight distance required to aviod head-on collision of two cars approaching from opposite direction at 100 and 80 kmph. Assume a reaction time of 2.5 seconds, coefficient of friction of 0.7 and a break efficiency of 50 percent, in either case.
OR- a)
Q2
- a)[6]
Explain PIEV theory of stopping sight distance.
- b)[6]
What is ruling gradient, what are the limiting values of IRC recommendations of ruling gradient? When limiting gradient is used?
- c)[6]
Desing speed of a highway is 100 kmph. There is a horizontal curve of radius 300 m on a certain locality. Calculate superelevation needed to maintain this speed. If maximum superelevation of 0.07 is not to be exceeded, calculate the maximum allowable speed on this curve as it is not possible to increase the radius. Safe limit of transverse coefficient of friction is 0.15.
