3. INDIAN ROADS DURING MONSOON

4. PROPOSED SOLUTION

5. INTROUCTION
 Self repairing roads are roads comes with built-in crack healing.
 Built up on the knowledge of material science and structural engineering.
 This will be a game-changer in road construction.

6. HISTORY
 Professor Nemkumar banthia, University of
British Columbia, isone of the greatest Indian
minds that have developed a technology that can
be used to make roads repair themselves.
 He pioneered the process of structural repair and
strengthinig using sprayed fibre reinforced
polymers.

7. MATERIALS USED
 High strength concrete
 Fibers with hydrophilic nano-coating

8. MECHANISM
Hydrophilic coating of fibers means they attract water and water act
as crack healers for this road

9. CHARACTIRISTICS
 This roads are 60% less thick than normal pavements
 About 60% of cement is replaced with flyash
 It comes with built-in crack healing.

10. CASE STUDY
 90 Km from Bengaluru toThondebhavi
 Constructed in 2015

11. ADVANTAGES
 It comes with built-in crack healing which leads to safe & comfortable
journey
 It is also 30% cheaper in terms of a first time cost
 These are cost effective, have greater longevity and are sustainable.
 Environment friendly

12. DISADVANTAGES
 This mechanism is limited to concrete pavements
 Skilled labour is required
 This should only limited to normal traffic roads

13. CONCLUSION
