Abstract

Hydraulic properties of geotextiles are controlled by the geotextiles' pore sizes, pore size distribution, and porosity. Because porometry characteristics of fabric are difficult to measure precisely, index tests have been developed that relate other fabric characteristics to hydraulic performance. Apparent opening size, permittivity, gradient ratio, and transmissivity are hydraulic properties currently being used as performance criteria for geotextiles. ASTM Committee D-35 on Geotextiles, Geomembranes, and Related Products is developing standard procedures for characterizing these properties.
