SUCTION VARIATIONS AND SOIL FABRIC OF SWELLING COMPACTED SOILS
This study addresses firstly, the soil fabric variations of loose and dense compacted samples during a single wetting and drying cycle between 0 and 287.9 MPa using mainly the Mercury Porosimetry Intrusion (MIP) tests. Two suction techniques were employed to apply this wide suction range: the osmotic technique for suctions less than 8.S MPa, and the vapor equilibrium or salt solution technique for suctions higher than 8.S MPa. Secondly, the Soil Water Retention Curves (SWRC) were predicted by the MIP test results for both loose and dense samples. A reasonable correspondence between MIP results and SWRC was found on the wetting path for the low suction close to saturation and on drying path for the higher suction.
