3. What Is pavement?
 Pavement is a hard surface that's covered in concrete
or asphalt, like a road or a driveway. ... In the
US, pavement most often refers to a road or street,
but it can also mean any paved surface, like a
sidewalk or paved area in a park. The word has a Latin
root, pavimentum, "level surface that's been beaten
firm."

4. TYPES OF PAVEMENT

5. FLEXIBLE PAVMENTS

8. TYPICAL LAYERS OF FLEXIBLE
PAVMENT

12. Factors Affecting Pavement Design
 Wheel load
 Axle configuration
 Contact pressure
 Vehicle speed
 Repetition of loads
 Sub grade type
 Temperature
 Precipitation

17. Types of Soil Tests for Road Construction
 In-situ Moisture Content.
 Specific gravity of soil.
 Particle Size Distribution (By wet sieving & pipette
method)
 Compaction test – Proctor test.
 California Bearing Ratio (CBR) Test

18. CONCLUSION
 Use of the innovative technology not only strengthened the
road construction but also increase the road life .
 Introduction of plastic waste as a flexible pavement.
 Plastic road would be a boon for India`s hot and extremely
humid climate where durable and eco-friendly roads which
will relive the earth from all type of plastic waste.
 Roads laid with plastic waste mix are found to be better
than the conventional ones.
 Plastic will increase the melting point of the bitumen.
 Rainwater will not seep through because of the plastic in
the tar . So , this technology will result in lesser road
repairs.
 Planting trees besides the roads laid to less pollution and
enhances the beauty of road.
