- 1. PLASTIC MODIFIED BITUMEN ROADS PRESENTEDBY: BIKASH MUDULI DEPT. CIVIL ENGG RAAJDHANI ENGINEERING COLLEGE GUIDED BY: MR.MADAN MOHAN MOHAPATRA HOD. CIVIL DEPARTMENT RAAJDHANI ENGINEERING COLLEGE
- 2. CONTENTS WHAT ISPLASTIC ? TYPES OF PLASTIC ? STEPS FOR USING PLASTIC IN ROADS ON SITE EXECUTION ADVANTAGES AND DISADVANTAGES OF PLASTIC ROADS CONCLUSION
- 3. WHAT IS PLASTIC A PLASTIC MATERIAL IS ANY OF A WIDE RANGE OF SYNTHETIC OR SEMI- SYNTHETIC ORGANIC SOLIDS THAT ARE MALLEABLE. THEY ARE USUALLY SYNTHETIC, MOST COMMONLY DERIVED FROM PETROCHEMICALS.
- 4. TYPES OF PLASTICS ELASTOMERS THERMOSETS THERMOPLASTICS
- 5. STEPS FOR USINGPLASTIC IN ROADS SEGREGATION CLEANING PROCESS SHREDDING PROCESS COLLECTION PROCESS
- 6. SEGREGATIO N PLASTIC WASTECOLLECTED FROM VARIOUS SOURCES MUST BE SEPARATED FROM OTHER WASTE. MAXIMUM THICKNESS OF 60 MICRONS.
- 7. CLEANING PROCESS PLASTICWASTE GET CLEANED AND DRIED.
- 8. SHREDDING PROCESS PLASTICSWILL BE SHREDDED OR CUT INTO SMALL PIECES. THE DIFFERENT TYPES OF PLASTIC WASTES ARE MIXED TOGETHER.
- 9. COLLECTION PROCESS THEPLASTIC WASTE REMAINING IN 1.5 TO 2 mm ARE COLLECTED AT ONE PLACE.
- 10. ON SITE EXECUTION THERE ARE TWO TYPES OF EXECUTION PROCESS OF PLASTICS. • WET PROCESS • DRY PROCESS
- 11. WET PROCESS BLENDINGOF WASTE PLASTICS BY DIRECT MIXING OF SHREDDED PLASTICS WITH HOT BITUMEN AT 160°C. MECHANICAL STIRRER IS NEEDED AS THE MIXING IS DIFFICULT BECAUSE OF DIFFERENCE IN VISCOSITIES OF MOLTEN POLYMER AND BITUMEN. ADDITION OF STABILIZERS AND PROPER COOLING ARE REQUIRED. SINCE THE WET PROCESS REQUIRE A LOT OF INVESTMENT AND BIGGER PLANTS. NOT COMMONLY USED.
- 12. DRY PROCES S THIS PROCESSIS DEVELOPED BY prof. R.VASUDEVAN. HE IS THE DEAN OF DEPT. OF CHEMISTRY IN THIAGARAJAR COLLEGE OF ENGINEERING.
- 13. THE AGGREGATEIS HEATED UP TO 170°C IN THE MINI HOT MIX PLANT. MINI HOT MIX PLANT AGGREGATE TRANSFERRED TO PUDDLING CHAMBER
- 14. THE SHREDDEDPLASTICS IS ADDED TO THE HOT AGGREGATE IN EQUAL PROPORTION. WASTE PLASTICS MIXED WITH THE HOT AGGREGATES
- 15. THIS PLASTICGET COATED OVER THE AGGREGATE UNIFORMLY. COATED AGGREGATE PLAIN AGGREGATE
- 16. IMMIDIATELY THEHOT BITUMEN WITH 160°C IS ADDED WITH THE MIXTURE. BEFORE BITUMEN MIX BITUMEN IS ADDED WITH COATED AGGREGATE
- 17. THE MIXTUREIS TRANSFERRED TO THE ROAD AND THE ROAD IS LAID. Road is being laid
- 18. CHARACTERISTIC OF PLASTICCOATED AGGREGATE LOS ANGEL’S ABRASION TEST – WEAR AND TEAR VALUES OF PLASTIC COATED AGGREGATE IF FOUND TO BE DECREASING WHILE USING PLASTICS. EG. 37% WITHOUT PLASTIC, 32% WITH 1% PLASTIC, 29% WITH 2% PLASTIC. SOUNDNESS TEST- THE PLASTIC COATED AGGREGATE, DID NOT SHOW ANY WEIGHT LOSS, HENCE IMPROVE THE QUALITY OF THE AGGREGATE.
- 19. Aggregate ImpactValue Plastics Improves Aggregate Impact Value. Helps To Improve The Quality Of Flexible Pavement Aggregate impact value % of plastic coating over aggregate Compressive strength (MPa) Bending strength (MPa) 10% 250 325 20% 270 335 30% 290 350 40% 320 390 BINDING PROPERTY
- 20. ADVANTAGES OF PLASTICROAD SIMPLE PROCESS, NO NEW MECHINARY IS REQUIRED. USE HIGHER PERCENTAGE OF PLASTIC WASTE. REDUSE THE NEED OF THE BITUMEN BY AROUND 10%. INCREASE THE STRENGTH AND PERFORMANCE OF THE ROAD. REDUSE THE COST AROUND Rs.5000/KM OF SINGLE LANE ROAD. GENERATE JOBS FOR RAG PICKERS. UP TO 10,00,000 CARRY BAGS DISSAPEARED IN ONLY 10Mtr. NO POT HOLES.
- 21. DISADVANTAGES TOXICS PRESENTIN THE PLASTICS WOULD START LEACHING AFTER SOME YEARS. ONCE THE ROAD STARTED TO USE,IT WILL REALESE THE FINE PARTCELS OF POLYMER.

- 24. CONCLUSION PLASTIC WILLINCREASE THE ADHESSIVE NATURE OF THE BITUMEN. NOT ONLY STRENGTHEND THE ROAD BUT ALSO THE ROAD LIFE. ECONOMICAL. INCREASED DURABILITY. ECO-FRIENDLY.
