JCE_V6_N3_RP1 Expansive Soil: Causes and Treatments Faezehossadat Khademi Jeff Budiman Journal on Civil Engineering 2249 - 0779 6 3 1 13 Expansive Soil, Swelling, Shrinkage, Causes of Expansive Soil, Treatments of Expansive Soil 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 the imposed 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.
