USE OF PLASTIC WASTE IN ROAD CONSTRUCTION
INTRODUCTION
plastic waste - hazard to the environment.
plastics waste - construction of flexible pavement
NATURAL RESINS
solids or semi solid materials
light yellow to darkbrown in colour
carbon, hydrogen and oxygen.
globules on the bark .
Various Resins Of Plastic
Polyethylene terephthalate (PET,PETE)
Density polyethylene(HDPE)
Vinyl(Poly vinyl chloride or PVC)
Low Density Polyethylene(LDPE)
Polypropylene(PP)
SEGREGATION
plastic waste collected from various sources must be separated from other waste.
Maximum thickness of 60 microns.
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..
ADVANTAGES OF PLASTIC ROAD
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
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
