plastic roads that defines a clean plastic free environment for our future with roads having a life of vast more than standard the major issue of this era is how to reduce the plastic IT IS SOMETHING THAT MAN HAS MADE BUT IT CANT BE DESTROYED ..AS LIKE IT IS A NON DEGRADABLE MATERIAL. how to get rid from it is a bigger issue in today's world.

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 USING PLASTIC IN ROADS
 SEGREGATION
 CLEANING PROCESS
 SHREDDING PROCESS
 COLLECTION PROCESS

6. SEGREGATIO
N
 PLASTIC WASTE COLLECTED FROM VARIOUS SOURCES MUST BE SEPARATED
FROM OTHER WASTE.
 MAXIMUM THICKNESS OF 60 MICRONS.

7. CLEANING PROCESS
 PLASTIC WASTE GET CLEANED AND DRIED.

8. SHREDDING PROCESS
 PLASTICS WILL BE SHREDDED OR CUT INTO SMALL PIECES.
 THE DIFFERENT TYPES OF PLASTIC WASTES ARE MIXED TOGETHER.

9. COLLECTION PROCESS
 THE PLASTIC 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
 BLENDING OF 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 PROCESS IS DEVELOPED BY
prof. R.VASUDEVAN.
 HE IS THE DEAN OF DEPT. OF CHEMISTRY IN
THIAGARAJAR COLLEGE OF
ENGINEERING.

13.  THE AGGREGATE IS HEATED UP TO 170°C IN THE MINI HOT MIX PLANT.
MINI HOT MIX PLANT
AGGREGATE TRANSFERRED TO
PUDDLING CHAMBER

14.  THE SHREDDED PLASTICS IS ADDED TO THE HOT AGGREGATE IN EQUAL
PROPORTION.
WASTE PLASTICS MIXED WITH THE HOT AGGREGATES

15.  THIS PLASTIC GET COATED OVER THE AGGREGATE UNIFORMLY.
COATED AGGREGATE PLAIN AGGREGATE

16.  IMMIDIATELY THE HOT BITUMEN WITH 160°C IS ADDED WITH THE MIXTURE.
BEFORE BITUMEN MIX
BITUMEN IS ADDED WITH
COATED AGGREGATE

17.  THE MIXTURE IS TRANSFERRED TO THE ROAD AND THE ROAD IS LAID.
Road is being laid

18. CHARACTERISTIC OF PLASTIC COATED
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 Impact Value
 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

20. ADVANTAGES OF PLASTIC ROAD
 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 PRESENT IN 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 WILL INCREASE THE ADHESSIVE
NATURE OF THE BITUMEN.
 NOT ONLY STRENGTHEND THE ROAD BUT
ALSO THE ROAD LIFE.
 ECONOMICAL.
 INCREASED DURABILITY.
 ECO-FRIENDLY.
