Interaction studies between geotextile and fill material

Abstract

As the growth in geotechnical science, there are a lot of new innovations that are used for solving geotechnical problems. One of those innovations is geotextile.This geotextile is often used in earth fill as reinforcement with function to increase the shear strength of existing fill and related with the interaction between geotextile and fill material. Based on this fact, this research is conducted to know the interaction of soil type to geotextile. The result of the research shows that all of the tested soil shear strength parameter comparison are below 1 (0.23; 0.29; 0.24 for C of clay comparison), (0.65; 0.77; 0.98 for ϕ of clay comparison), (0.53; 0.66; 0.67 for ϕ of sand comparison), and (0.53; 0.66; 0.67 for ϕ of coarse aggregate comparison). So it could be concluded that the shear strength of fill material and geotextile material is lower than the shear strength of fill material without geotextile.
