| Popis: | 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, Australia. Specimens treated with an optimum lime content (OLC) that was found to reduce swell potential were selected to investigate the SWCCs. Static compaction tests were conducted to establish the virgin compression surface. Hyprop (Meter Group, Pullman, Washington), filter paper, and the chilled mirror hygrometer were used to measure the SWCC at and below the surface at different net stress levels. To interpret the volumetric behavior of untreated and treated soil using the SWCC, swelling and collapse values were measured at various initial moisture contents and stress levels. The test results found that although the treated specimens were stabilized with lime at OLC, significant collapse and swelling potential were obtained when the lime-treated specimens were prepared at high suction value and wetted under low net stresses. |
