The present investigation deals with the study of separation efficiency of geotextiles used for civil engineering works by means of the comparison between pore size distribution of fabrics and particle size analysis of used soil. For plotting the integral and differential distributions of fabrics pores, a special apparatus was designed. This apparatus was used to characterize water wickability behaviour of geotextile fabrics. The method is based on the determination of the volumatric absorbed water and water height penetrated through multi-layers of geotextile fabrics using capillary phenomena at equilibrium condition. And consequently pore size distribution of fabrics could be plotted. Also an experimental technique (dry sieving of soil with and without fabric) used to evaluate fabric separation efficiency is investigated. The experimental results are compared to the calculated separation efficiency obtained using the pore size distribution. The calculated values of separation efficiency (passage percent of soil) was found to be fairly close to those observed experimentally.
