An Overview. Expansive soils, also known as soils with high shrink-swell potential, are common in various geographic regions, especially the central portion of North America. These soils are fine-grained clay minerals comprised of illites, kaolinites, or montmorillonites. The net effect of their constituency is such that they have the unique ability to absorb relatively large volumes of water and therefore expand.

Clay soils are a great example of an expansive soil. Aiming at the requires to the evaluation of expansive soils in practice, an evaluation index system is developed and attribute measurement functions are constructed to calculate attribute measurement of single index and synthetic attribute measurement that is used to recognize the expansibility of expansive soil. 2021-02-06 Figure 2.15: Expansive soil showing popcorn texture -----23 Figure 2.16: Soil designation based on relative density -----26 Figure 2.17: USCS plasticity chart for laboratory classification of fine grained soils Expansive soil covers an appreciable part of Ethiopia. It constitutes a real financial risk and disruption to the quality of life.

The ultimate goal of the second phase will be to establish up-to-date design guidelines that offer specific strategies for highway construction on swelling soils and

When saturated during the rainy season, the soil swells into a gooey, plastic substrate that exerts extensive pressure on shallow-footing foundations, typical of many residential structures. The states that are most affected by expansive clay soils are Texas, Louisiana, Mississippi, Florida, Kansas, Missouri, Colorado, and Tennessee but the reality is expansive clay soils impact homes in all 50 states. What is an “Expansive Soil”? Expansive soils contain minerals such as smectite clays that are capable of absorbing water.

expansive soil movement is approximately 1, 05,988 millions of rupees, which exceeds the combined average of annual damages from floods, hurricanes, earthquakes and tornados. [1] In this paper various types of damages caused by expansive soils are given. Thorough

Hence, it becomes very essential for a practicing geotechnical engineer to Expansive clay is a clay soil that is prone to large volume changes (swelling and shrinking) that are directly related to changes in water content. Soils with a high content of expansive minerals can form deep cracks in drier seasons or years; such soils are called vertisols. Any soil whose volume changes are moisture sensitive is normally considered as an expansive soil. Expansive soils are regarded as problematic soils as they affect the stability of structures founded on them. Hence, it becomes very essential for a practicing geotechnical engineer to appropriately identify and characterise such soils.
