The experts needed on a roadway project are:
- Traffic engineer
- Pavement engineer
- Surveyor
- Geotechnical Engineer
- Environmental expert
- Hydraulic engineer
- Bridge engineer
- Highway engineer
- Quantity surveyor
- Planning Engineer
- Project Manager
- Quality engineer
Answer to Question-3 :
Parameters of horizontal alignment and vertical profile are
- Terrain of the land
- Design speed
- Environment
- Aesthetics
- Design Vehicle
- Sight distance
- Safe travel
- Economics of project
- Sustainability
Vertical Curve is needed for smooth transition of travel for vehicle between two different gradients.
Vertical curves :
1.Summit curve
2.Valley curve
Answer to Question-4 :
Superelevation is required when the vehicles pass through horizontal curves with sharp turn or smaller radius to counteract the centrifugal force created of moving vehicle towards outer side of the road and keep the vehicle travel within the roadway.
