Estimating the Retention Curve of a Compacted Soil through Different Testing and Interpretation Methods

The paper reports the results of a study about the hydraulic properties of a self-weight compacted medium-grained soil. The investigation was based on both physical modelling and element volume testing, using different suction measurement techniques. The paper shows the efficacy in the assessment of the soil retention properties of the use of the filter paper technique and of low capacity tensiometers to measure the soil suction in different suction ranges.
