ESTIMATION METHOD OF PENETRATION RESISTANCE OF GEOMEMBRANE AND GEOTEXTILE

Abstract

The applications of geomembrane and geotextile are expanding on soil structures in railway, highway and so on. Thier typical functions are reinforcement and stabilization of soil structure, drainage and separation of soil and water. Regarding separation, penetration resistance of geosynthetics is one of the most important functions. However, there are no confirmed estimation method for penetration resistance. In this study, we developed the penetration resistance tester (PR tester) and by using this tester, we got the value of penetration resistance. And moreover, we got the master curve of penetration resistance, under the time-temperature superposition principle. By using this method, we can estimate penetration resistance under wide range of penetration rate.
