2. INTRODUCTION
Sustainability is a wide acknowledged idea in current
development situation. Despite the fact that the
development business is changing in a significant way as
far as machines and goods utilized, development price
had arise alongside the adverse effect to the ecosystem.
Coir fibre is accessible in plenty that accomplishes coir
fibre exceptionally sensible as a support material in soil
and concrete.In addition, it is a good technique for the
transfer of coir sleeping pad wastage that diminishes the
interest for additional wastage exchange framework and
reduction the heap on existing landfills and incinerators.

3. REVIEW OF LITERATURE
 Beeghly J et al. (2003), investigated for appropriate soils, lime- fly
ash can offer cost saving by reducing material cost by up to 50% as
compared to Portland cement stabilization. For low cohesive soil
used with lime and fly ash stabilization can be economically
engineered for long term performance.
 Aggarwal and Sharma (2010), used bitumen coated jute with
different fibre lengths and varying percentages to reinforce soil and
found that jute fibre decreases the MDD with the improvement in
OMC. They obtained Maximum CBR value (2.5 times than plain
soil CBR) with 0.1cm in length and 0.8% jute fibre.

4.  Maury et al. (2007), it represents a study to analyze both un-soaked
and soaked CBR value of soil increases with the increase in fibre
content. The %age of coir fibre in each soil sample was gradually
increase like 0.25%,0.50%0.75%, 1 % and various test are
performed like UCS and CBR. Soaked CBR value found to
enhances from 4.75% to 9.22%, unsoaked CBR values found to
enhance from 8.72% to 13.55%. UCS value found to increase from
2.75kg/cm2 to 6.33kg/cm^2 It was concluded that the usage of coir
fibre reinforced soil improved the properties of soil and its strength.

5. RESEARCH GAP
The existing review of literature has been reviewed thoroughly in
which the present researcher found that the various fibres has been
used together for soil stabilization and provided best results. In this
connection the present researcher would try to focus on the separate
use of coconut fibre in soil stabilization and what would be the
results of separate use of coconut fibre and will made a comparison
between the various fibres used together with the separate use of
coconut fibre. In advancing future, the examination on fibre fortified
soils exhibited that such material may be a useful and best method
for sub grade stabilization in flexible pavements. In this association
the present researcher would attempt to focus on the separate
utilization of coconut fibre in soil reinforcement and what might be
the after-effects of independent utilization of coconut fibre and will
made a correlation between the different strands utilized together
with the separate utilization of coconut fibre.

6. OBJECTIVES
 To study the coconut fibre
 To find the Results on use of coconut fibre for soil
reinforcement.
 To compare the results with together use of fibres and
separate use.
 To study the stress - strain relationship properly which has not
been properly done yet.
 To study the shear strength of soil due to use of various
percentages of coconut fibre.

7. METHODOLOGY
 Identification of suitable site.
 Collection of soil samples.
 Evaluation of Liquid limit, Plastic Limit, SPT value of soil.
 Reinforcement of other soil samples using various proportions of
fibre as well as ash powder. Determination of CBR value of fibre
reinforced soil.
 Comparison of the CBR values of the reinforced and unreinforced
soils.
 Conclusion.
