## Question

State the scope of construction materials in transportation.

## Short answer

Construction materials in transportation include aggregates, bitumen, and concrete for roads; steel rails and sleepers for railways; structural steel and concrete for bridges; and concrete pavements for airports. Proper selection ensures strength, durability, and low maintenance.

## Answer

Materials are the basis of transport infrastructure.

- **Roads:** aggregates, bitumen, asphalt, cement concrete, soil and geotextiles for pavement layers.
- **Railways:** steel rails, concrete or timber sleepers, ballast stone.
- **Bridges and tunnels:** structural steel, reinforced and prestressed concrete, bearings and cables.
- **Airports and ports:** rigid concrete pavements, piles, steel and protective coatings.
- **Drainage and markings:** pipes, culverts, paints and signboards.

Knowledge of these materials ensures strength, riding quality, durability and low maintenance cost.
