Sliding Shear Testing of Nonwoven Geotextile Reinforced Pilani Soil

Abstract

Geotextiles and related products support many civil engineering applications. Geotextile is permeable textile material. Geotextile is made up of natural as well as of synthetic fibers which could be woven or nonwoven. Woven geotextiles consist of fibers or yarns of a polymer that are oriented in two perpendicular directions, one over the other. There are four main fiber types which are used to manufacture woven geotextiles: monofilament, multifilament, slit-film and fibrillated fibers. Nonwoven geotextiles consist of discrete fibers which may be oriented or randomly distributed. There are also different fiber types used to manufacture nonwoven geotextiles: continuous filaments; and staple fibers. Nonwoven geotextile made up of synthetic fiber and used as reinforcing agent in local soil has been used in present study. Sliding shear testing of nonwoven geotextile reinforced experimental soil was conducted at four different water contents to investigate the effect of water content on adhesion and on interface friction angle under these conditions. Testing was done under fully drained conditions.
