Analysis of Mechanical Properties of Soil Using Geotextiles Sarmistha Rudra Paul

In this book, the behavior of two-layer soil (Sand-silt Soil) that were reinforced with some geosynthetics is investigated. Large-scale California Bearing Ratio tests are to be performed by some scientists on unreinforced and reinforced samples with different geosynthetics. The results show that depending on the characteristics of the geosynthetics, the inclusion of these materials may increase or decrease the shear strength parameters of the interface of two-layered soils. It implies that the geosynthetic-reinforced soils in the sub-base layer of roads are so sensitive to the characteristics of geosynthetics and will perform better than non-reinforced soils and consequently the load-carrying capacity of the basement will improve only if the appropriate geosynthetics are used. However, geosynthetics show more reinforcement efficiency under higher vertical stresses. Increasing the relative density of the sub-grade would also cause the geosynthetic (geotextiles and geonets) reinforcement to be more effective.
