Transmissivity and Permittivity Performance of Geotextile Laid Horizontally in Embankment

Abstract

Geotextile, which is a sheet-like drainage or permeable material in both a normal direction to the plane and its cross-sectional direction, is often applied recently to the usage of the embankment constructed using a high moisture content cohesive soil including a poor surplus soil produced in a construction site or the backfilling material needed to be dewatered in cases of fully saturated condition. In this study a laboratory model test experiment is carried out to investigate a fundamental hydraulic behavior of soil-geotextile composite system and the effects of thickness of spunbonded geotextile, overburden pressure, different gradation of soil, degree of compaction (apparent density of soil on tansmissivity and permittivity of the complex system.
