Investigation and modeling of unsaturated flow through swelling soils
… theory of water movement through an unsaturated, swelling soil has been developing for a number of years, the efficiency of the results has been limited, and the developed models have suffered from a lack of a mechanism to reliably define water flow and experimental techniques for measuring the …

Detection of expansive soils using remote sensing in Brits North-West Province South Africa
Expansive soils generally pose a significant geological hazard, which causes damage to civil infrastructure that could amount to billions of rand every year. Traditionally, expansive soils have been mapped and characterized using methods such as X-ray Diffraction (XRD) and standard engineering …

The effect of fly ash on clay
… the effect of mixing fly ash with regional swelling of clayey soils indicated these mixtures were superior in certain engineering properties. Mixtures of clay soil, and fly ash at 10, 20, 30, and 40 percent exhibited reduced plasticity and swelling characteristics while the unconfined …

Characterization of the Engineering Properties and Economic Potential of the Transitional Clay Unit of the Ripley Formation, Northeast Mississippi
Expansive soils, throughout Mississippi and the U.S., have long been a source of problems within the engineering and construction industries, leading to billions of dollars in damage annually. Along with being a source of problems, the clays throughout Mississippi are also of economic importance, …

Evaluation and Laboratory Measurement of the Coefficient of Permeability in Deformable, Unsaturated Soils
… of permeability function for unsaturated soils. The research program commenced with a literature review on the coefficient of permeability function. The permeability function for a constant volume porous medium was categorized into empirical equations, macroscopic models and statistical …

A Comprehensive Investigation on Microscale Properties and Macroscopic Behavior of Natural Expansive Soils
… and two laboratory stabilized expansive soils were selected as the study objects. The roles of some microscale properties in determining the macroscopic behavior of volume change and shear strength have been thoroughly examined through experimental work including three dimensional water …

Swelling behaviour of unsaturated expansive clays
… two available approaches for predicting the swelling behaviour of unsaturated expansive clays:<br/>(i) simplified empirical relationships for rapidly identifying swelling soils and<br/>(ii) a more accurate prediction method suitable for design purposes and based upon experimentally measured …
