  2. 2. CONTENTS...IntroductionWhat is plastic ??Field trailsMeritsDe-MeritsConclusionBasic process
  3. 3. INTRODUCTIONPlastic use in roadconstruction is not new.Recent studies in thisdirection have shown somehope in terms of usingplastic-waste in roadconstruction i.e., Plasticroads. Plastic roads mainlyuse plastic carry-bags,disposable cups and PETbottles that are collectedfrom garbage dumps as animportant ingredient of theconstruction material.When mixed with hotbitumen, plastics melt toform an oily coat over theaggregate and the mixtureis laid on the road surfacelike a normal tar road.
  4. 4. Plastic Roads In Bangalore
  5. 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. 6. Discarded thin plastic carry bags are amenace. In town they clog drains, cause flooding,choke animals that eat them and are unsightlyStrewn across fields, they blockgermination and preventrainwater absorption by soil.Recycling plastic by meltingreleases fumes, and is onlypossible 3-4 times. Toxic contentsmight leach into recycled waterpots or water-pipes. Shreddedplastic is a great additive for tarroads. Discarded thin-plasticcarry-bags are a menace. In townthey clog drains, cause flooding,choke animals that eat them andare unsightly
  7. 7. Plastic waste, hazardous to earth
  8. 8. Basic Processes:1. Segregation.2. Cleaning process.3. Shredding process.4. Collection process .
  9. 9. 1. SEGREGATIONPlastic waste collected from various sources must beseparated from other waste Maximum thickness of 60 microns. Segregation process
  10. 10. 2. CLEANING PROCESS:Plastic waste get cleaned &dried
  11. 11. 3. SHREDDING PROCESS:The plastic waste will beshredded or cut into smallpiece. The different types of plastic wastes are mixed together Shredding process
  12. 12. 4. COLLECTION PROCESS:The plastic waste retaining in 2.36 mm iscollected.
  13. 13. Field TrialsThere are two typeof field trials:1. DRY PROCESS2.WET PROCESS
  14. 14. 1. Dry processThe aggregate is heated to 170 ° C in theMini hot Mix Plant .
  15. 15. The shredded plastic will be addedin equal proportions
  16. 16. Immediately the hot Bitumen 60/70 or 80/100 grade (160°C) is added.The mixture is transferred to the roadand the road is laid.
  17. 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. 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. 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. 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
