...Abhishek Rawat; Wiebke Baille; Snehasis Tripathy; Tom Schanz This paper presents a newly designed column-type experimental device for investigating the coupled thermo-hydro-mechanical behavior of expansive soils. Sensors and monitoring instruments facilitated continuous and nondestructive...

...Amin Soltani; An Deng; Abbas Taheri; Asuri Sridharan This study examines the effects of two types of recycled tire rubber of fine and coarse categories on the swell–shrink–consolidation behavior of a highly expansive soil mixture. Each of the two rubber choices were incorporated into the soil...

... for comparison. Practical applications are demonstrated in two ways. First, select results are analyzed to assess the swelling potential of the four clays using an existing methodology based on total suction testing. Second, aspects related to the adsorption kinetics of expansive soils are evaluated by analyzing...

...: expansive soils, cyclic strain, swelling, shrinkage, laboratory testing Expansive soils that occur in the arid and semi-arid parts of the world are subjected to periodic ground movements from seasonal moisture content changes. These ground movements manifest as heave during wet season, and shrinkage during...

...TS Sikh The purpose of this paper is to provide information pertinent to post-development depth-of-moisture increase in expansive soils underlying developed sites. In southern California, the developments are generally accompanied by irrigation around buildings and other improvements. Local...

...SN Abduljauwad; GJ Al-Sulaimani Knowledge of the swell potential of expansive soil at the outset of an investigation can be helpful in avoiding possible damage to the structure. A review is presented of several methods that have been proposed to identify swell potential and test techniques, which...

...SA Habib; D Karube An experimental study has been conducted to study the swelling pressure behavior of expansive soil in both vertical and lateral directions simultaneously under controlled suction. A series of one-dimensional consolidation tests was carried out on compacted soil specimen using...

...AE Dif; WF Bluemel An approach was developed to study the swell-shrinkage behavior of expansive soil samples in the laboratory under the action of the actual load to which the soil will be subjected in the field. The fatigue phenomenon due to cyclic drying and wetting has been under investigation...
