This document discusses the use of waste plastic in the construction of flexible pavements. It notes that plastic production is increasing rapidly in India and most plastic waste is not recycled. Using waste plastic as a binder in road construction could help reduce pollution while saving resources. The document outlines a methodology where waste plastic is used to modify bitumen. It presents test results showing that modified bitumen with 10% plastic waste performs better than plain bitumen, with increased durability, softening point, and load carrying capacity. The use of waste plastic in roads could successfully dispose of plastic waste while providing cost savings for road construction.

3. NEED OF TIME
TO REDUCE POLLUTION
TO REDUCE WASTE
TO RE-USE WASTE
TO SAVE NATURAL RESOURCES
TO PREVENT ENVIRONMENTAL DEGRADATION
THUS TO GET GOOD ATMOSPHERE

4. ROAD NETWORK IN INDIA
India has a road network of over 3.314 million
kilometres of roadway.
Third largest road network in the world.
As of 2008, only 49% of the network consisted of
paved roads.
India plans to spend approximately US$70 Billion by
2013 to modernize its highway network.
Primary material required for road construction are
rubble, boulder, murrum, aggregate and bitumen.

9. RESULTS
Comparison between plain bitumen and modified
bitumen (10% plastic waste):

10. COMPARISON
Material cost comparison for 1km road
Total material cost reduction=7.99%

11. EXAMPLE’s
Wajgaon-Kharde Road, MDR-39, Dist. Nashik (LENGTH
146M)
plastic model was successful on major roads in Bangalore
0f about 600 km of roads
1. Shankar Mutt Road,
2. K H Road,
3. M G Road (towards Trinity Circle),
4. J C Nagar Road, Miller's Road,
5. Cunningham Road,
6. Rajarajeshwari Junction,

12. CONCLUSION
The polymer bitumen blend is a better binder compared to plain
bitumen.
Increase the durability and performance
Increased Softening Point and decreased Penetration Value with
a suitable ductility.
When used for road construction it can withstand higher
temperature. Hence it is suitable for tropical regions.
It has decreased Penetration Value. Hence its load carrying
capacity is increased.
No toxic gas is produced.
Disposal of waste plastic will no longer be a problem.
It is a good saving too.
Hence, A better road can be constructed by using waste plastics .
