In this presentation you will find what is jute Geo-textile, how it is manufactured and application of jute Geo-textile. It contains some of the case studies from INDIA.

1. SOIL IMROVEMENT BY
USING JUTE GEOTEXTILE
Presented By- Vinod kumar

2. WHAT IS JUTE GEOTEXTILE
 Jute Geotextiles (JGT) is a natural variant of man-made geotextiles
loosely called ‘Geo-synthetics’.
 Jute geotextiles (JGT) has emerged as a strong alternative to synthetic
geotextiles for many civil engineering applications.

3. JUTE PLANTS

4. JUTE FIBRES

5. ADVANTAGES OF JUTE GEOTEXTILE
 Abundant quantity ( INDIA is producing 20lakh
m/t of jute per year ).
 Great moisture retention capability.
 Ease of installation.
 Bio-degradable properties.
 Lower cost compare to synthetic geotextile.
 High initial tensile strength.

6. APPLICATION AREAS OF JGT
 Rural road pavement construction.
 Reinforcement of soil.
 Control of railway track settlement.
 Slope stabilization.
 Protection of river banks, seashores etc.

7. Pavement construction

8. Slope stabilization

9. WHAT DO YOU MEAN BY SOIL
STABILIZATION
 Soil stabilization is a way of improving the
weight bearing capabilities and performance
of in-situ sub-soils, sands, and other waste
materials in order to strengthen road surfaces.

10. SOIL STABILIZATION
 Soil modification:
Improvement of soil behavior.
 Soil stabilization:
Increases strength and structural values.

11. METHODS OF SOIL IMPROVEMENT
 Mechanical Stabilization.
 Chemical Stabilization.
 Bitumen Stabilization.
 Cement Stabilization.
 Lime Stabilization.
 Stabilization By Grouting.
 Sand Stabilization.

12. OBJECTIVE OF USING JGT FOR SOIL
IMPROVEMENT
 To study the influence of jute geotextile on California bearing
ratio.
 To study the effect of JGT on Water content, void ratio and
compression index
 To study the effect of geotextile as a arrests migrating of soil
particle and allows water to permeate across It.
 To study the strengthening of soil of low bearing capacity.

13. TECHNICAL FUNCTION
 Checks subsidence of A pavement by separating and preventing intermixing
of the soft subgrade and the harder sub-base.
 May control reflective cracking of pavements.
 Provides effective drainage system.
 Enhances strength and stability of high road embankment built with
materials of uncertain behaviour.
 Highly water absorbent; absorbs water about 5 times its dry weight.
 Slopes of embankments with problematic soil may be stabilized by applying
jute geotextile.

14. CASE STUDY
APPLICATION IN KAKINADA PORT AREA
 Jute geotextile was used to strengthen a weak subgrade in Kakinada
port area.
 Geotextiles are particularly effective where roads are constructed over
weak subgrade soils, having CBR value less than 2.0.
 Unpaved roads, in particular, are subjected to severe rutting and loss of
aggregate, resulting in heavy maintenance cost.

15. LAYING OF JUTE-REINFORCED PAVEMENT
 A test section, 360m long, 21.6m wide. On either side of the road, lm deep trenches
were excavated to a width of 1.2m to anchor the jute geotextiles.
 Rolls of jute geotextiles were sewn to make a width of 28m with an overlap of 150mm.
 The jute geotextile was spread over the road and the trench.
 Trenches were backfilled with the clay excavated for the formation of trenches.
 Sand was laid on the jute geotextile and compacted with smooth-wheeled rollers.
Thickness of compacted sand bed was 1.2m. This constituted the base course.
 A layer of compacted gravel was placed on the sand layer to a compacted thickness of
100mm.

18. INDEX PROPERTIES OF SOIL

19. EFFECT ON WATER CONTENT
 The high initial water content of the soil indicated that the soil was very soft.
 Water content decreased after the laying of geotextiles over a period of time,
indicating the increase in the effective stress.

20. EFFECT ON DRY DENSITY

21. EFFECT ON PROGRESS OF CONSOLIDATION

22. EFFECT ON CBR VALUE

23. CROSS-SECTION OF PAVEMENT IMPROVED

25. CONCLUSION
 There is significant improvement in the CBR value of soil
reinforced with Jute Geotextile.
 Water content, void ratio and compression index decreased.
 Jute geotextile is very effective in weak subgrade soils in
reducing their compressibility and increasing their strength.
 In the present case, an unpaved road laid on the reinforced
soil is still giving good service even after a lapse of 7 years.
