ENGINEERING OF MULTILAYER JUTE SANDWICH FABRIC FOR POTENTIAL APPLICATION IN THE FIELD OF GEOTECHNICAL ENGINEERING

Paved road ways that include the carriageways along with the shoulders have been constructed for more than a century. Their basic design methods and construction techniques have undergone some changes with the development of modern engineered products as per end use requirements. Out of these the development of geotextiles in the past three decades had provided the strategies for enhancing the overall performance of the paved roadways. Several varieties of Geotextiles either in the form of woven or non-woven have since been developed for a number of end uses mainly as underlay in road construction for strengthening the pavement structure by increasing the soil compactness apart from the other end uses. Some fabrics are also being used as interlayer for the prevention of the reflective cracking in the road. All the Geotextiles that are being used in the geotechnical engineering like road construction, soil erosion control, slope management, agro textiles etc. are either woven or nonwoven. Now a days 3D or multilayer fabrics are being extensively used as technical textiles which have great market potential. As per the need of the day, combined fabric of jute woven and nonwoven of different number of layers and area density have been produced and optimized in respect to their geotechnical property parameters for potential application in the field of geotechnical engineering. This paper delineates the engineering of multilayered jute fabric, which is a combination of woven and nonwoven jute fabric and it
