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 perfo- -rmance 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.
9. 1.SEGRAGATION plastic waste collected from various sources must be separated from other waste. Maximum thickness of 60 microns. SEGREGATION PROCESS 9
10. 2. CLEANING PROCESS Plastic waste get cleaned and dried. cleaning process 10
11. 3. SHREDDING PROCESS will be shredded or cut into small piece. the different types of plastic wastes are mixed together shredding process 11
12. 4. COLLECTION PROCESS the plastic waste retaining in 2.36 mm is collected. collected plastic 12
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 . Heated aggregates 14
18. 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. 100% improvement in fatigue life of roads. Reduced penetration and ductility, a higher softening point, less rutting and cold cracking. 18
21. 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 20
