2. INTRODUCTION
• India has one of the world's largest railway and roadway network
transporting millions of people every year.
• India’s most of the road pavement are made up of bituminous material
and failure occurs in the pavement due to different soil condition,
temperature variation and material etc.
• In use bitumen material in road pavement so many problem in the road
pavement potholes, shrinkage, many type of cracking

3. GENERAL CAUSES OF PAVMENT
FAILURES
• Defects in the quality of materials used.
• Defects in construction method.
• Increase in the magnitude of wheel loads and the number of load repetition
due to increase in traffic volume.
• Environmental factors including heavy rainfall, soil erosion, water table,
snowfall, forest action, etc…

4. PROBLEM IN THE REAL LIFE
• Cracking in pavements
• Potholes in pavements
• Shrinkage in pavements
• Swelling in pavements

5. BLOCK CRACKING TRANSVERSE CRACKING
LONGITUDINAL CRACKING FATIGUE CRACKING
 Cracking in pavements

6.  Potholes in pavements

7.  Potholes in pavements

8.  Potholes in pavements

9. Shrinkage in pavements

10. Swelling in pavements

11. WHY THIS PROBLAMS OCCURS IN
ROAD PAVEMENT
• In India has a most of road pavement are a flexible pavement and Rigid
pavements so when the loads are apply on pavement in a few years load is
properly and after pavement is failure.
FLEXIBLE PAVEMENTCOMPOSITION LAYERS OF FLEXIBLE PAVEMENT

12. • When the load apply in pavement, load is transfer to ground by safely.
• but a after few year lower sub grade is failure in ground.
LAYERS OF RIGID PAVEMENT RIGID PAVEMENT SLAB

13. • When the load apply in pavement, load is transfer to ground by safely.
• but a after some time lower sub grade is failure in ground.
LOAD DISTRIBUTION IN FLEXIBLE PAVEMENT LOAD DISTRIBUTION IN RIGID PAVEMENT

14. • As show in fig. when the load is apply in road pavement aggregate are
secreted.
• That’s why in a road pavement upper layer is disturb so generated Cracking,
Potholes, Shrinkage, Swelling etc…

15. WHAT IS THE SOLUTION IN THE REAL
LIFE
• Use a geosynthetics material in a road pavement.
• The American Society for Testing and Materials (ASTM) has defined
geosynthetics : “A planar product manufactured from polymeric material
used with soil, rock, earth, or other geotechnical engineering related material
as an integral part of a man-made project, structure, or system.”
• Common types of geosynthetics are geogrids, geotextiles, geocomposites,
geonets, and geomembranes and our review would concentrate on
geotextiles and geogrids

16. TYPES OF GEOSYNTHETIC MATERIAL
• Geogrids
• Geotextiles
• Geocomposites
• Geonets
• Geomembranes
• Geotextiles
• Geogrids

17. DIFFERENT TYPES OF GEOSYNTHETICS MATRRIALS

18. • The polymers used in the manufacture of geotextile fibers are made from
polypropylene (83%), polyester (14%), polyethylene (2%) and polyamide,
nylon (1%).
• The melt process accounts for most geotextile fibers; these include
polyolefin, polyester, and nylon.

22. DIFFERENCE BETWEEN GEOSYNTHETICS AND
WITHOUT GEOSYNTHETIC
CONTROL IN AGGREGATE LOSES BY GEOSYNTHETICS

23.  In current time in Gujarat has a so many place use
geosynthetic material in road pavement
• Surat bardoli highway Use Geotextile material

24. ADVANTAGE OF GEOSYNTETIC
MATERIAL
• Easily accessible in market
• Life of road pavement is more
• It’s simple technic not hared
• Not require good skill person
• It is economic in financially condition
• It is less cost compeer to without geosyntetic material
