Quantifying Properties and Variability of Expansive Soils in Selected Map Units
A study of 12 expansive soils in four major physiographic provinces in Virginia was initiated to examine and quantify the relationship between shrink-swell potential, shrink-swell indices, and soil properties. The mineralogy classes, soil series, and (physiographic provinces, parent materials) …

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 …

Enhancing the engineering properties of expansive soil using bagasse ash, bagasse fibre and hydrated lime
Expansive soils exhibit massive volume change against fluctuations of moisture content. Shrinkage and expansion of soil can commonly take place near the ground surface, where it is directly subjected to seasonal and environmental variations. Construction of civil engineering structures on expansive …

Delineation of Landslide Hazard and Development of Mitigation Tools in a Vulnerable City
… underlain by young, soft sedimentary rocks and soils. In the city of Gisborne, the expansion of residential blocks into steeper terrain in peri-urban areas has required improved capacity for the characterization and monitoring of slope stability. Landslides have affected several properties and …

Assessment of lime-treated clays under different environmental conditions
Natural soils in work-sites are sometimes detrimental to the construction of engineering projects. Problematic soils such as soft and expansive soils are a real source of concern to the long-term stability of structures if care is not taken. Expansive soils could generate immense distress due to …

A scanning electron microscopy study of natural engineering soil
… wide variety of naturally occurring engineering soils. The mode of viewing used is the Scanning Electron Microscope, chosen because of its versatility in terms of its magnification range and ability to accept a wide range of soil textures. The sample preparation method used is the air-drying, …

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, …
