- Plastic roads can be made from waste plastic which is a more durable and cost-effective alternative to normal roads. The process involves shredding waste plastic, mixing it with heated bitumen, and laying the mixture on roads. - Mixing plastic with bitumen increases the melting point and flexibility of roads while overcoming brittleness. This results in roads with longer lifespans that are more resistant to damage from rain. - Plastic roads require less bitumen, have improved bonding between materials, prevent moisture absorption and cracking, and show greater compressive strength than normal roads. They provide a smoother ride and more durability.

2. What Is plastic & Why do we need plastic?
 Plastic is material consisting of any of a wide rangeof syntheticor semi-synthetic organic compounds that aremalleable and so can be molded into solid objects.
 A material that contains one ormore organic polymersof large molecularweight, solid in its finished state and at some state while manufacturingor processing into
finished articles, can be shaped by its flow.
 Plastic is mainlyused for packaging.
 Plastic is veryuseful because it can be coloured, melted, shaped, squashed, rolled into sheets or madeinto fibres plastics.
 It is cheap in coast.
 Plastic is non-biodegradable material.

3. Waste From Plastic
 Bottles, containersand packingstrips etc. is increasing day byday as a result amountof waste plastic also increases, this leads to various environmentalproblems.
 It is estimated that, India generates 1.88lakh tons of garbage every day of which 8% is plastic waste.
 40%of generated plastic is burned, land filled ordumped.

4. Making of road by waste plastic
 The technology was developed by the ‘Plastic Man’ of India,
Prof Rajagopalan Vasudevan, Professor of Chemistry at
Thiagarajar College of Engineering, Madurai.
 Roads constructed by this technology is more durable and
very cost-effective.
 Mainly It reduces the waste plastics which is hazardous for
environment.
 The roads also show greater resistance to damages caused
by heavy rains.

5. Process of making road by waste plastic
1. Waste plastic is made powder and varying percent plastic is mixed with bitumen.
2. Plastic increase the melting point of the bitumen and makes the road flexible during winters resulting in its long life.
3. By mixing plastic with bitumen the brittleness overcomes and elastic nature enhances.
4. There are two important processes used for bitumen mix flexible pavement, they are
-Dry process
- Wet process
5. When it gets coated uniformly over the aggregate within 30 to 60 seconds, giving an oily look.

6. Process of making road by waste plastic
Dry Process
• For the flexible pavement, hot stone aggregate (170°C) is mixed with hot bitumen (160°C) and the mix is used for
road laying.
• The aggregate is chosen on the basis of its strength, porosity and moisture absorption capacity as per IS coding.
• The aggregate, when coated with plastics improved its quality with respect to voids, moisture absorption and
soundness.

7. Process of making road by waste plastic
Wet Process
• In this process the waste polymer directly added with bitumen and heated up to temperature of 170°C.
• Then the hot mix is then cooled up to 120°C into another chamber, which is then added to the aggregate in
paddling chamber.
• After addition of modified bitumen at 110°C on aggregate, it is then laid on the road and then spreader material is
compacted by 8 ton roller.
• Since the wet process require a lot of investment and bigger plants so not commonly used.

8. Process of making road by waste plastic
 Segregation
Plastic waste collected from various sources must be separated from other waste.
Maximum thickness of plastic must be a 60 microns.

9. Process of making road by waste plastic
 Cleaning Process
Plastic waste get cleaned and dried.

10. Process of making road by waste plastic
 Shredding Process
Shredded or Cut into small piece.
Then different types of plastic wastes are mixed together.

11. Process of making road by waste plastic
Collection process
The plastic waste retaining in 2.36 mm is collected.

12. Results
 The results of the studies on the extraction of bitumen by dry process showed that the bonding between stone
aggregate and bitumen is improved due to the presence of polymers.
 Use of higher percentage of plastic waste reduces the need of bitumen by 10-12%.
 This prevents the moisture absorption and oxidation of bitumen by entrapped air. This has resulted in reduced
rutting, ravelling, and there is no pothole formation.

13. Comparison of road construct by plastic waste
with normal Road
 The cost difference for the roads laid with compound as against without it is Rs. 500 / Cubic Meter.
 Saving of 10% by weight of bitumen.
 Increase in compressive strength.
 Indirect tensile strength values increased by 3 times
 Provide smooth riding surface displaying much better durability

14. Future Scope
• In this process almost 10% of solid waste used in the making of plastone. So we are trying to
increase the % of plastic and reduce the % of bitumen.
• We are trying to make a plastic roads that are more durable, climate friendly. Which is currently
using by a Netherland.
