Abstract

Geotextiles made of natural fibres like jute have been found to be effective in improving geotechnical characteristics of soil and are being extensively used for various technical end-uses viz. rural road construction, protection of river banks, stabilization of embankments, erosion control, management of slopes, consolidation of soft soils etc.Over the years several research and developmental studies alongwith different projects of national and international status have been carried out to establish the efficacy of jute geotextile (JGT) in satiating the geotechnical requirements. One such encouraging response is CFC/IJSG/21 Project, funded by Common Fund for Commodities, Netherlands and its execution is being carried out jointly by the two neighbouring countries India and Bangladesh. The overall objective of the project is to determine and demonstrate the effectiveness of jute geotextile in the two pre-identified promising applications like rural road construction and soil erosion control to demonstrate their competitiveness with the otherman-madematerials generally in use. In execution of the project, Department of Jute and Fibre Technology (DJFT), University of Calcuttahad been mainly entrusted with the testing of the different samples produced by the different Jute Mills of West Bengal, India as per the specifications laid by National Jute Board, Ministry of Textile, Govt. of India, the Project Executing Agency (PEA). DJFT has carried out all of the testing work of the woven JGT samples required for the specified geotechnical applications and made a comprehensive test report and comparative analysis of the test results. The Project Investigator has shared the test results with the PEA, time to time, alongwith the different Facilitating Agencies (FAs) of India for the purpose of finalisation of specification of the Jute Geotextile for the above mentioned three specific applications. The testing of the developed JGT samples of different functional categories is followed by respective field trials along with vigilant monitoring process at different sites to evaluate their performance for the purpose of standardization of the same to fulfil the requirement of global acceptance.One of the prime criteriafor global recognition of the reports and analysis of the test results of the samples carried out by any laboratory is to get accredited by a statutory certifying body of national or international status following anytesting standard like ASTM, CEN etc. Heading in this direction, DJFT, IJT, CU has already undertaken a project under the supervision of National Jute Board (NJB), MoT, GoI alongwith Indian Rubber Manufacturers Research Association (IRMRA), Mumbai, India, as consulting agency to get their geotextile laboratory National Accreditation Board for Testing and Calibration LaboratoriesNABL) accredited and is undergoing the procedurefor getting NABL certified. The testing of the exhumed samples is also taking place simultaneously for assessing the performance andsustainability of the developed products.
