Abstract: In recent years, geotextile has been used as one of the modern technology in landfill for several functions such as geotextile filter, geotextile cushion, geotextile separator, geotextile gas vent etc. In landfills, geotextiles are subjected to a complex range of acidic and alkaline solutions generating from waste and leachate. To survive these chemical attacks in subsoil environment, geotextile is required to be enough strong and resistant. Due to the waste and leachate characteristics, it is very essential to determine the chemical resistance of geotextile used in landfills. The aim of this paper is to determine the effects of chemical aging on the tensile strength and strain of synthetic geotextile. Experimental evaluation on the properties of nonwoven polypropylene geotextile is conducted under the influence of acidic (pH 0.5) and alkaline (pH 14) condition. This particular pH range signifies highly intense chemical aging. The geotextiles were immersed in the acidic and alkaline solution for 15, 30, 60, 90 and 120 days. Tensile strength and strain have been evaluated for both chemically treated samples which will provide a better understanding of the durability of geotextile to be used in landfills.
