Abstract - India is one of the leading coir producing
countries. Coir industry provides employment to people belonging to weaker sections of the society in rural and coastal areas. To protect the traditional coir industry and to make it possible to meet the challenges in structured development of the nation, the development of new products and new horizons of varied applications of the existing products is necessary. At present, Coir Geotextiles account for only a fractional share of the global market of Geotextiles. While the world focus is shifting to natural Geotextiles, India as a producer of Coir Geotextiles, has much to gain by using it for meeting the domestic as well as global demands. The objective of present work is to study physical properties of sub grade soil and coir geotextile fibre. The study pertains to ascertain the variation in index properties of soil when mixed with plain and treated coir fibre at different proportions To determine engineering properties of the soil mixed with plain and treated coir fibre at different proportions. To determine the variation in California Bearing Ratio (CBR) values at different percentage of plain and treated coir fibre. To study the effect of plain and treated coir fibre at different proportions on unconfined compression strength of the soil (UCS).So that that the present study will help out in ascertaining variation of the coir fibre length on the engineering properties of the soil.
weaker sections in specific areas of the coir producing countries, for example in southern states of India viz., Kerala, Karnataka, Tamilnadu, Andhra Pradesh and also in the west and south of Sri Lanka. Coir is a versatile natural fibre extracted from the fibrous husk that surrounds the coconut. The fibres are tough, strong and extremely resistant to fungal and bacterial decomposition. Fibre length varies from 0.3 mm to 250mm; but to an average ranges from100 mm to 200mm. Coir cross sections are highly elliptical and non uniform with average diameter 0.25 mm. In spite of low cellulose content, coir fibre has a very close fibre structure which account for its better durability compared to other natural fibres. Coir being a biodegradable and environment friendly material is virtually irreplaceable by any of the modem polymeric substitutes. With the diversification of the products and evolvement of new technologies for the production of fibres, the export of coir products has been increased tremendously. Though the demand for coir geotextiles is increasing, the total coir exports from India comprises only less than 3% of it. The close involvement of the local governments, with the support of the public research institutions and private enterprises is required for innovation, manufacturing and marketing of coir.

1.INTRODUCTION
Several authors have reported various successful improvement techniques of stablization using coir fibres
Coir is derived from the excerpt of the fruit of the coconut tree "Cacos nucifera Lynn" grown in the tropical countries mainly for the high oil content of the endosperm (copra). The English word "coir" comes from the Malayalam word “kayaru”. Large production areas, in particular, can be found along the coastal regions in the wet tropical areas of Asia, in the Philippines, Indonesia, India, Sri Lanka, and Malaysia. Total world production of coconut increased substantially from nearly 35 million tons in 1980 to more than 50 million tons today. Yield varies from region to region with an average of 70 to 100 nuts and a maximum of 150 nuts per year. The kernel (copra, coconut water and shell) comprises 65% of the total weight, while the husk contributes only 35%. Despite their low trade value, the fibres provide significant economic support to populations especially to © 2017, IRJET

Brown et. al. [1] (as reported by Ling et al 2001) conducted a series of tests to study the effectiveness of a polypropylene geogrid in improving the performance of pavement, such as resistance to rutting, reflective cracking and fatigue cracking. They also reported that the geosynthetic reduced the rut depth by 20 % to 58 %. Burd et al.[2] emphasised the importance of the friction shear characteristics in soil geosynthetic friction tests. Their work highlighted the importance of these parameters in overall behavior of reinforced unpaved road. Schurholz [3] reported the durability of coir geotextile. According to him the coir geotextiles retain 20% of their original tensile strength after one year in incubator tests ISO 9001:2008 Certified Journal
