11. IMPROVED CHARACTERISTICS OF PLASTIC COATED AGGREGATE
NIL SOUNDNESS
NIL MOISTURE ABSORPTION
IMPROVED AGGREGATE IMPACT VALUE
IMPROVED ABRASION VALUE
IMPROVED CRUSHING VALUE
Dr. R. Vasudevan
ZERO VOIDS

17. Salient features of the Process
Multi layer films can be used
No new machinery required
No Industry Involvement
No granulation or Powdering of plastics- only shredding
In-situ process
Eco friendly process
Only stone is modified and not Bitumen
Scraps can be used
Value addition to waste plastics
No need for land filling and Incineration
Carbon dioxide emission prevented
Dr. R. Vasudevan

18. SALIENT FEATURES – WASTE PLASTICS BITUMEN ROAD
STRENGTH INCREASED BY 100%
NO POT HOLES, RUTTING AND RAVELLING FORMED
WITHSTAND HEAVY LOAD
DECREASED BITUMEN CONSUMPTION - CONSTRUCTION COST REDUCED
VALUE ADDITION TO WASTE PLASTICS
NIL MAINTENANCE COST FOR MORE THAN 7 YEARS
NO EFFECT OF RADIATION LIKE UV
LIFE OF THE ROAD - DOUBLED

Dr. R. Vasudevan

23. Benefits of laying plastic roads – Rural Roads
Rural Roads lakhs Km if these roads are constructed as plastic tar roads – we need 24.5 lakhs tones of waste plastics!!!!!!-
We prevent nearly 75 lakh tones of Carbon Dioxide entering our atmosphere by burning waste plastics
We save 24.5 lakhs tons of bitumen
We save nearly Rs crores worth of bitumen
No maintenance cost for ten years
Total waste plastics used for packing material per in India is around 20 lakhs tones only.
The plastic available is insufficient for laying rural roads only.
In a nut shell the Government provides not only good roads but also uses all the waste plastics and reduces carbon dioxide – bitumen usage.
Not less than crores saved
To convert all roads in India to plastic roads we need import plastic waste from other countries
If all roads are converted in to plastic roads ??????????
