QUESTION: 1

The mechanical extra widening required for 10.5 m wide pavement on a horizontal curve of radius R metre is given by 

where l is the length of wheel base of vehicle in metres.

Solution:

Mechanical widening 
where, n = no. of lanes
For 10.5 m wide pavement,
n=3

Solution:
QUESTION: 6

Transition curves are provided on the approach to horizontal curves in order to

Solution:
QUESTION: 7

Transition curve is provided in horizontal alignment

Solution:
QUESTION: 8

The ideal form of curve for the summit curve is

Solution:

Circular summit curve is ideal as the sight distance available throughout the length of circular curve is constant.

QUESTION: 9

The off-tracking of a vehicle having a wheel base of 6.0 m and negotiating a curved path of mean radius 25 m is

Solution:

QUESTION: 10

The important factor considered in the design of summit curves on highways is

Solution:

When a fast moving vehicle travels along a summit curve, the centrifugal force will act upwards, against gravity and hence a part of the pressure on the tyres and spring of the vehicle suspensions in relieved. So there is no problem of discomfort to passengers on summit curves, particularly because the deviation angles on roads are quite small. The only problem is designing summit curves is to provide adequate sight distances. The stopping sight distance or the absolute minimum sight distance should invariably be provided at all sections of the road system and so aiso on summit curves.
