Soil suction and swell behavior of chemically treated expansive clays
<p>"Expansive clay soils have caused significant damage throughout the world. Chemical stabilizing agents have been used to reduce the swelling potential of expansive clay soils. However, how chemically treating soils affects the matric and osmotic suction of soils has not been investigated. …

Volume change behavior of clay soils and the effect on discrete fractures
… fractures in fine-grained soil such as clays in response to changing environmental conditions. Fractures serve as conduits for moisture transfer, which can lead to substantial shrinking and swelling of the surrounding fracture boundary soils. These volume changes, in turn, affect …

Geophysical Assessment of Subsurface Soil Conditions Using Capacitively Coupled Resistivity
… locations for drilling and sampling such as expansive clay layers and anomalies (sinkholes, unknown landfills, etc.) rather than uniformly sampling across a site. CCR surveys were performed at Alpena, Arkansas along a highway expansion project changing US 62 from a two lane to four lane …

Development of a constitutive model for a heaving clay from Rosebank
Heaving clays are partially saturated soils composed of a high fraction of the montmorillonite clay mineral. When exposed to free water they undergo volumetric expansion, which often results in differential movements at the surface and damage to building structures founded on the clay. The economic …

Assessment of lime-treated clays under different environmental conditions
… 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 their volume change in response to a slight change in their water content. On the …

Determinación de las características de fricción en el contacto suelo-geotextil a diferentes succiones, mediante equipos de laboratorio singulares
… was carried out with remoulded samples of an expansive clay (locally known as “peñuela”) with 7% of sodium montmorillonite, yielding LL=74 %, PI=37%, free swelling of 14 %, swelling pressure of 0,31 MPa and initial suction of 1,9 MPa. The friction tests comprised this soil and 3 different …

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 …
