Question 1

________ percentage of Indian rails routes are electrified.

Accepted Answer

C

Question 2

________________ is the predominant gauge used by Indian railways.

Accepted Answer

Broad gauge is the predominant gauge used by Indian railways, facilitating a wider track for stability and higher speed.

Question 3

Sleepers (ties) are mostly made up of

Accepted Answer

B

Question 4

________         forms the trackbed upon which railroad ties (sleepers) are laid.

Accepted Answer

Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is used to bear the load from the railroad ties, to facilitate drainage of water, and to keep down vegetation that might interfere with the track structure.

Question 5

The surface of the head of each of the two rails can be maintained by using a

Accepted Answer

Rail grinders are used to maintain the surface of the head of the rails by removing irregularities and imperfections, ensuring a smooth surface for the trains to run on.

Question 6

The track and ballast form the

Accepted Answer

The track and ballast together are referred to as the "permanent way" in railway terminology, indicating the permanent infrastructure provided for trains to operate.

Question 7

The longest railway platforms is

Accepted Answer

Gorakhpur Railway Station in Uttar Pradesh, India, holds the record for the longest railway platform in the world.

Question 8

The design of horizontal and vertical alignments, super elevation, gradient is worst affected by ________

Accepted Answer

The design of horizontal and vertical alignments, super elevation, gradient is primarily affected by the speed of the vehicle. This is because the speed influences the necessary curvature, stopping sight distance, and the degree of super elevation required to safely navigate a road at a given speed.

Question 9

The most raised portion of the pavement is called ________

Accepted Answer

The most raised portion of the pavement, typically found at its center to facilitate drainage, is referred to as the crown.

Question 10

The extra width of pavement is provided on ________

Accepted Answer

The extra width of pavement is provided on horizontal curves to accommodate the increased path length taken by vehicles, especially those on the outer lanes, and to ensure safe maneuvering around the curve.

Question 11

Transition curve is introduced in

Accepted Answer

Transition curves are introduced between a straight path and a circular curve to provide a gradual change in curvature, enhancing safety and comfort by reducing the suddenness of entering a curve from a straight path.

Question 12

The most important factor that is required for road geometrics is ________

Accepted Answer

The speed of the vehicle is the most important factor that is required for road geometrics. This is because the speed of the vehicle will determine the stopping distance, the sight distance, and the curvature of the road.

Question 13

The design speed of NH on a cross slope of up to 10% is ________

Accepted Answer

The design speed for National Highways (NH) on a cross slope of up to 10% is typically 100 kmph, as per standard highway design guidelines.

Question 14

A part of pavement raised with respect to one side keeping the other side constant is called ________

Accepted Answer

Super elevation is the banking of a road or a railway track where the outer edge is raised, providing a necessary centripetal force to counteract the centrifugal force of vehicles or trains taking the curve, enhancing safety and comfort.

Question 15

The main purpose of providing camber is

Accepted Answer

Camber is provided on roads to facilitate drainage by allowing storm water to run off the surface, preventing water accumulation and potential damage.

Question 16

The legal axle load of the design vehicle used in India is?

Accepted Answer

The legal axle load for a single axle with dual wheels in India is typically 8.2 tonnes.

Question 17

In India, the type of traffic assumed to design pavements is?

Accepted Answer

In India, pavements are designed assuming a mixed traffic flow, which includes a variety of vehicles such as cars, buses, trucks, motorcycles, bicycles, and pedestrians, all sharing the road. This diversity in traffic types necessitates a design that can accommodate the varying loads and speeds.

Question 18

The final choice of stabilisation technique is based on ________

Accepted Answer

The final choice of stabilization technique is often based on cost considerations, as it determines the feasibility and sustainability of the project.

Question 19

The flexural strength is based on

Accepted Answer

The answer of The flexural strength is based on
...

Question 20

How many types of challenges are encountered in bitumen stabilisation?

Accepted Answer

There are three main types of challenges encountered in bitumen stabilization: material-related challenges, construction-related challenges, and performance-related challenges.
