Review of Expansive Soils

Journal of the Geotechnical Engineering Division, 1974
Numerous man-made structures around the world have been subjected to considerable damage due to differential heave from moisture absorbed by expansive clay foundation soils. It has been estimated that the annual cost of damage from expansive soils in the United States alone is $2.3 billion. The actual heave is a function of many factors, e.g., climatic

Insights into the shallow landslide mechanism of expansive soil slope induced by freeze-thaw cycles and snowmelt infiltration

Canadian geotechnical journal (Print)
For rigorous understanding the shallow landslide mechanisms and deformation characteristics of expansive soil slopes, a comprehensive in-situ monitoring platform is established.

Repairing expansive soil channel slope with soilbags

Geosynthetics International, 2022
Shallow slope failure often occurs in expansive soil channel slopes because of the strong swelling–shrinkage behavior of the expansive soils and the well-developed fissures.

Study of Expansive Soils and Residential Foundations on Expansive Soils in Arizona

Journal of Performance of Constructed Facilities, 2011
Construction on expansive soils is challenging and thus prone to some problems and litigation. The engineering community makes extensive use of local experience and empirical procedures to address these problems. Although there has been extensive study of expansive soils and foundations on expansive soils, data related to performance of residential ...

Soil–environment interactions modelling for expansive soils

Environmental Geotechnics, 2016
Water content and matric suction changes in unsaturated expansive soils due to environmental variations contribute to the overall volume changes (shrinkage or swelling). The soil movements cause tilt in trees, highway surfaces, building foundations and pipelines and pose problems to the functionality of the infrastructure.

Expansive soils: TRL’s research strategy

2020
This paper describes some aspects of a TRL programme of research on expansive soils. The aim of the research programme was to provide practising engineers with guidance on design and construction of roads built on or with expansive soils. Particular emphasis was placed on the development of improved identification procedures, both in the laboratory and

Engineering properties of expansive soil

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2005
The components of expansive soil were analyzed with EDAX, and it is shown that the main contents of expansive soil in the northern Hubei have some significant effects on engineering properties of expansive soil. Furthermore, the soil modified by lime has an obvious increase of Ca2+ and an improvement of connections between granules so as to reduce the ...

Microstructure of Omani expansive soils

Canadian Geotechnical Journal, 1999
The fundamental factors controlling the expansive nature of Omani soils are their characteristics with respect to geology, mineralogy, engineering, and microstructure. The first three factors have been extensively studied, however, the fourth has not yet been fully investigated and no work has been published on this aspect. Therefore, this paper deals
