Answer:
Flexible Pavement: A pavement which is consists of asphalt or bituminous mixing with aggregate, which have a very low flexural strength and is flexible in structural behavior is known as flexible pavement.
Rigid Pavement: A pavement which is consists of cement concrete slab which have capable of considerable flexural strength is known as rigid pavement.
Factors affects Super Elevation:
1. Design Speed
2. Curve radius
3. Number of travel lane
