Abstract: Sewer infrastructures that are backfilled with available onsite expansive soils may be exposed to damages due to seasonal ground movements. Therefore, for deep excavated trenches located in nontrafficable areas, the ...

Abstract: The swell-collapse mechanism of residual basaltic clay in both untreated and stabilized with lime conditions was investigated. For treated specimens, the optimum lime content (OLC) was found based on swell potential ...

Abstract: Utilizing natural expansive clays that are available on-site as sewer trench backfill can cause destructive deformations due to volume changes, which are caused by seasonal climatic changes. Such deformations result in ...

Abstract: In practice, it is quite common for soils to be mixed and compacted at moisture contents lower than the optimum moisture content (OMC) or lime content less than the optimum lime content (OLC). This study investigates the ...

Abstract: This paper investigates the influence of lime stabilization of an expansive clay based on volumetric behavior and the soil–water characteristic curve (SWCC). The selected soil was a residual clay located in Victoria, ...
