Geotextiles are relatively new construction materials that have been increasingly used particularly in infrastructure applications. This study aims at testing the effectiveness of using three different types of geotextiles in applications requiring drainage systems and comparing their performance to a control (unprotected) system as well as a traditional drainage method. Experiments are conducted to examine the time-to-discharge of the systems. Also, flow versus discharge of each of the systems is calculated as well as its discharge profile. Microscopic analysis of the geotextiles themselves before and after the drainage is carried out to examine the structure of the geotextiles material on one hand and to pinpoint the retention of fine aggregates upon drainage on the other. A brief cost study is provided to recommend the pros and cons of each construction material introduced as a function of drainage characteristics.
