Abstract

Aging of geotextile, which is widely used as reforming medium in structures, attracted a great deal of attention in recent years, as it is very important to the stability of the whole work. Especially, the prediction of geotextile’s aging-time has become one of the focuses nowadays. In this study, four types of nonwoven geotextiles was used in tests, which are heat bounding, needle punched, chemical adhesive, and supporting by thread. The modified EPA 9090 test method was applied to compare the chemical resistance in pH 8 for agricultural wasting water in Syria. The immersion conditions are 30~90 days under 25°C and 50°C respectively. On other hand, chemical resistance of these nonwoven geotextiles was estimated by the average retentions of mechanical properties before/after exposure in the above chemical solution. However, the relied mechanical properties are grab tensile response, trapezoidal tear strength, and CBR puncture strength testes. In addition, we have compared between specimens in related to pore size volume, thickness, weight per m2, and row material. Transmissivity of geotextile for drainage were slightly decreased in pH8 solution. Finally, needle punched nonwoven geotextile has the best resistance to the tensile, tear, and puncture before and after aging.
