Effect of Particle Size of Sand on the Interface Shear Behavior of Sand and Non-Woven Geotextile

Mahmud Sazzad, Rima Parvin

Abstract


Soil-geosynthetic interface is the weakest zone for shear failure. It is influenced by size, shape, density and water content of sand. It is also influenced by the properties of geosynthetic such as texture and structure. This paper explores the influence of the size of sand on the behavior of sand-geotextile interface. Three types of sands namely coarse, medium and fine sand and non-woven geotextile were used in this study. Several interface direct shear tests on these materials were performed using a direct shear box modified for interface testing. The test results depict that the peak interfacial friction angles between the sand particles and geosynthetic material (geotextile) depend on the relative size of sand particles. The interfacial friction angle for fine sand is higher than that of the coarse sand with the non-woven geotextile. Interfacial strength efficiency of fine sand is 19.45% greater than that of coarse sand and is 11.38% greater than that of medium sand for the same type of geosynthetic material. Interfacial friction angle between sand and non-woven geotextile is 0.70 to 0.90 times of sand to sand friction angle for dry condition.
