ABSTRACT

The basic test schedule comprised four stages of resilient testing. Firstly each sample is tested at a low water content state, corresponding to an approximate matric suction of 15 kPa, after which water was added to maximum retentive capacity and further on to saturated (or soaked) conditions. The samples were tested after each addition. Maximum retentive capacity corresponds to the maximum amount of water the sample can retain without draining, given the soil specific soil-water characteristic curve and sample geometry. After the soaked state, the samples were allowed to drain freely and tested for the fourth and final stage. In Table 1 water contents for the various stages are summarized.
