Index Term — Geo-textile. Vertical permeability, Fabrication,

Abstract — Now-a-days geo-textile materials have been used worldwide for solving geotechnical engineering problems associated with soil and water conservation work. Among the various properties of the geo-textile, the hydraulic properties are of major importance from the engineering point of view. This paper presents a simplified mechanism for the design and fabrication of vertical permeability test apparatus to determine the vertical permeability of geo-textile. The vertical permeability test apparatus has been fabricated and installed as per ASTM standard D 4491-99. The test apparatus has been manufactured in the department of civil engineering using locally available materials. After installation of the apparatus, the cross-plane permeability test for the geo-textile material has been performed. The permeability of geo-textile for different thickness obtained from this apparatus satisfies the standard values of permeability
