The changes in gradient and vertical curve are covered under which type of alignment?
The changes in gradient and vertical curve are covered under the vertical alignment, whereas the remaining three are covered under horizontal alignment.
The improper alignment of road will not result in
The increase of population does not depend on the alignment of the road, whereas improper construction and maintenance lead to accidents.
The basic requirement of alignment should be
The alignment of the road should be short, safe, easy and economical for users and engineers
The economical option during the construction of a road around a hill is
The most economical option is to provide a road around the hill. In this alternative approach is not advisable as it has to pass either through the hill or nearby the hill.
Obligatory points through which the alignment should not pass are
The obligatory points through which alignment should not pas include religious structures and costly structures because destroying them would require a lot of compensation.
The desire lines are prepared for the study of
The desire lines are lines which study the traffic flow from origin and destination.
Which of the following types of roads are most preferred for highways?
The most preferred type of road is bituminous roads. They are cheap for initial construction when compared to other type of surfaced roads.
The stability of slopes is considered while designing
The slope stability is important during design of hill roads ,because it may have a danger of landslides.
The coefficient of lateral friction as recommended by IRC is
The coefficient of lateral friction recommended by IRC is 0.15 and it lies between 0.3-0.4 for longitudinal friction.
The resisting length should be kept
The resisting length should be kept as low as possible for gradient purposes, if it is maximum then there will be a problem with the gradient.
