INSPIRATION

Nowadays roads are usually paved with bituminous pavements upon a suitably compacted soil subgrade . But in due course of time the subgrade generally gets damaged due to various natural as well as artificial calamities. So it is often emphasized to improve the subgrade characteristics using certain additional materials such as waste plastic bottles, natural and artificial fibres, tyre chips, etc. As India lies in a sub tropical zone availability of coconut is in abundance. The coconut husk which is usually wasted could be used for improvising the subgrade characteristics as it has various favourable properties such as cheap availability, high mechanical strength, etc .In addition to this coconut fibre is relatively water proof and is one of the few natural fibres salt water and microbial attack. So coconut fibre reinforced subgrade is often considered to be a better option in comparison with the normal subgrade.
