This document discusses using plastic waste in road construction. Plastic roads involve mixing shredded plastic waste like plastic bags and bottles with hot bitumen. Field trials show plastic can increase road strength and reduce costs. Advantages include using more plastic waste, reducing bitumen needs, and increasing road strength and lifespan. However, there are also disadvantages like toxic chemicals potentially leaching from the plastic and noxious gas releases during construction. The conclusion is that plastic roads could help strengthen infrastructure while improving the environment if the disadvantages around leaching and emissions can be addressed.

3. INTRODUCTION
Plastic use in road
construction is not new.
Recent studies in this
direction have shown some
hope in terms of using
plastic-waste in road
construction i.e., Plastic
roads. Plastic roads mainly
use plastic carry-bags,
disposable cups and PET
bottles that are collected
from garbage dumps as an
important ingredient of the
construction material.
When mixed with hot
bitumen, plastics melt to
form an oily coat over the
aggregate and the mixture
is laid on the road surface
like a normal tar road.

5. What is plastic??
 A plastic material is any of a wide range of
synthetic or semi-synthetic organic
amorphous solids used in the manufacture of
industrial products. Plastics are typically
polymers of high molecular mass and may
contain other substances to improve
performance and/or reduce costs. Monomers
of plastic are either natural or synthetic
organic compounds

6. Discarded thin plastic carry bags are a
menace. In town they clog drains, cause flooding
,choke animals that eat them and are unsightly
Strewn across fields, they block
germination and prevent
rainwater absorption by soil.
Recycling plastic by melting
releases fumes, and is only
possible 3-4 times. Toxic contents
might leach into recycled water
pots or water-pipes. Shredded
plastic is a great additive for tar
roads. Discarded thin-plastic
carry-bags are a menace. In town
they clog drains, cause flooding,
choke animals that eat them and
are unsightly

7. Plastic waste, hazardous to earth

8. Basic Processes:
1. Segregation.
2. Cleaning process.
3. Shredding process.
4. Collection process .

9. 1. SEGREGATION
Plastic waste collected from various sources must be
separated from other waste
 Maximum thickness of 60 microns.
Segregation process

10. 2. CLEANING PROCESS:
Plastic waste get cleaned &
dried

11. 3. SHREDDING PROCESS:
The plastic waste will be
shredded or cut into small
piece.
 The different types of
plastic wastes are mixed
together
Shredding process

12. 4. COLLECTION PROCESS:
The plastic waste retaining in 2.36 mm is
collected.

13. Field Trials
There are two type
of field trials:
1. DRY PROCESS
2.WET PROCESS

14. 1. Dry process
The aggregate is heated to 170 ° C in the
Mini hot Mix Plant .

15. The shredded plastic will be added
in equal proportions

16. Immediately the hot Bitumen 60/70 or 80
/100 grade (160°C) is added.
The mixture is transferred to the road
and the road is laid.

17. 2. Wet process
 Waste plastics by direct mixing with hot
bitumen at 160 ° C .
 Mechanical stirrer is needed.
 Addition of stabilizers and proper cooling.
 Since the wet process require a lot of
investment and bigger plants .
 Not commonly used..

18. Advantages of plastic roads
 Use higher percentage of plastic waste.
 Reduce the need of bitumen by around 10%.
 Increase the strength and performance of the
road.
 Reduce the cost to around Rs. 5000/Km. of single
lane road.
 Generate jobs for rag pickers. Develop a
technology, which is eco-friendly .
 100% improvement in fatigue life of roads.
 Reduced penetration and ductility, a higher
softening point, less rutting and cold cracking

19. DISADVANTAGES OF PLASTIC ROADS
:
 1. Cleaning process Toxics present in the co-
mingled plastic waste would start leaching .
2. During the road laying process In the
presence of chlorine will definitely release
noxious HCL gas .
 3.After the road laying It is opined that the
first rain will trigger leaching. As the plastics
will merely form a sticky layer, (mechanical
abrasion). The components of the road, once
it has been laid, are not inert

20. CONCLUSION:
 Plastic will increase the melting point of the
bitumen .
 use of the innovative technology not only
strengthened the road construction but also
increased the road life .
 Help to improve the environment .
 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
