Soil water retention curves of a silty clayey sand compacted at different dry density

The study of the hydraulic behaviour compacted soils in partially saturated conditions is essential for understanding engineering performance geotechnical structures such as river embankments. paper presents results an experimental focusing on effects initial water content and dry density soil retention curve (SWRC) volume change a mixture under loading. For this purpose, specimens at different contents(dry, wet optimum content), chosen basis standard Proctor compaction test, were used. Specimens composed 70% Ticino sand (TS) 30% Pontida silt (PON) have been tested. This heterogeneous silt, that usually constitute embankments tributaries Po (Italy). SWRCs along drying paths performed by means evaporation tests starting from gained permeameter tests. investigation void index during variation tested was estimated calliper photographic comparison. Changes are consistent with changes specimen condition while exhibited end test always negligible.
