Geotextiles have witnessed unrivalled growth worldwide in recent years in the field of different civil engineering constructions. The world of Geotextiles includes mainly non-biodegradable synthetic materials which are not environmentally compatible. With the increasing human awareness on environmental pollution aspects, biodegradable Jute Geotextile is increasingly gaining ground over its synthetic non-biodegradable counterpart. Though Jute is advantageous for its complete biodegradability in one hand but on the other hand it is disadvantageous for its poor microbial resistance and quicker biodegradation particularly under moist soil conditions, when applied as Geotextiles under soil. Therefore, it is a great challenge to the present researchers to make jute more microbial resistant (rot resistant) keeping its biodegradability intact during its performance period. Thorough investigation and study regarding the improvement of the durability of natural Jute Geotextile reveals the fact that though several attempts including chemical treatments have been made to enhance the life expectancy of jute fabrics yet these methods were neither found to be suitable nor techno-economically viable. Therefore, in order to accomplish the objective and based on the researchers’ report of satisfactory thermal compatibility between hot bitumen and jute nonwoven fabrics, in the present study Bitumen emulsion with essential additives has been applied following a special technique, apart from the conventional method, on the Grey Jute Nonwoven Fabrics in different add on percentages to make a comparative assessment of the performance of both Grey Jute Fabrics and Bituminized Jute Nonwoven Fabrics by Soil Burial Test as per the BIS standard test method. The test results revealed that the durability and performance of the Bituminized Nonwoven Jute Fabrics are much better than that of Grey Jute Nonwoven Fabrics. © 2014, The Institution of Engineers (India).
