The expansive soil problems lead to structural and geotechnical engineering challenges all over the world. Expansive soils are the type of soils which their volume changes considerably depend on their water content. It is worth mentioning that, the expansive soil problems can occur in both humid environments and arid/semi-arid soils. Buildings, roads, pipelines, and other structural members have always been subjected to damages resulted from expansive soils which this damage is even more than twice the damage resulted from floods, hurricanes, earthquakes, and tornadoes. Understanding the behaviour and characteristics of these types of soils can help scientists control their mposed damages to the structure. This paper is a comprehensive study on expansive soils, its nature, shrinkage-swell behaviour, as well as expansive soil causes and treatments. Geotextile reinforced earth technique is a very effective ground improve technique because of its cost effectiveness, easy adaptability and reproducibility and workability etc.In this project reportwork, order to investigate the behavior of geosynthetic-reinforced soil (GRS), a series of laboratory experiments were conducted on GRS samples made up of two different types of soils and a woven filament geotextile. The California Bearing Ratio (CBR) and unconfined compressive strength of the GRS mass were the parameters examined to evaluate the performance of the GRS samples. Soil reinforced with randomly distributed discrete woven filament geotextile at different aspects ratios of layers of 0,1,2,3.The focus of the tests was to study the effects of the vertical spacing of the reinforcement and the relative compaction of the granular soil on the performance of the GRS mass. Further more, the well-compacted granular soil reinforced with closely spaced geotextile not only has a higher compressive strength compared to that with widely spaced reinforcement, but also exhibits both ductile and flexible failure mode making it a desirable composite material for the construction of supporting structures.
