ENHANCEMENT OF ENGINEERING PROPERTIES OF SAND BY USING JUTE FIBRE AS A SOIL STABILIZER

Abstract

Soil is a base of structure, which actually supports the structure from beneath and distributes the load
effectively. If the stability of the soil is not adequate then failure of structure occurs in form of settlement, cracks etc.
Sub grade soil is an essential part within the pavement structure because it provides support for that pavement from
beneath. The qualities of sub grade soil are very important in the perception of pavement structure. Elevated earth can
be a composite material that's a mix of soil and reinforcement, placed to address the developed tensile stresses plus it
enhances the resistance within the soil for the finest stress. Jute fibre is a promising reinforcement for use in
composites on account of its low cost, low density, high specific strength and modulus, no health risk, easy
availability, renewability and much lower energy requirement for processing. In recent years, there has been an
increasing interest in finding new applications for jute fibre reinforced composites that are traditionally used for
making ropes, bags, hessians, sacking, mats, and carpet. The object of the present investigations is to study the
strength characteristics of sand of western Rajasthan stabilized with cheap and readily available material like Jute
fibre. Sand which covers a big part of western Rajasthan is weak in strength and possesses problems in construction
of road. Soils are permeable materials because of the existence of interconnected voids that allow the flow of fluids
when a differencein energy head exists. This study discusses the possibility of stabilization of sand using jute fibre as
admixture. The varying percentage 0.10%, 0.20, 0.50%, and 1% of strips of Jute fibre mixed with sand of different
densities 1.54gm/cc, 1.56gm/cc and 1.58gm/cc (M.D.D.). All the C.B.R. Tests were conducted at different mix
compositions of jute fibre and sand of different dry densities as arrived from Standard Proctor Test. On the basis of
the experiments performed, it is determined that the stabilization of sand using jute fibre as admixture improves the
strength characteristics of the sand so that it becomes usable as construction of embankment.
