Granular material is, perhaps the most common construction material used in civil engineering,being an important constituent in road constructions, railways, embankments, foundations, buildings etc. Thispaper presents results from triaxial testing, at various water contents using constant confining pressure, of twodifferent continuously graded granular materials with maximum particle size 90 mm and 63 mm, respectively.Furthermore, water retention properties of the unbound materials are presented and examples of water distri-butions in a common construction are shown. From the results presented, it can be concluded that increasedwater contents cause a reduction in resilient modulus and an increase in strain ratio. The distribution of watercontent in the vertical direction is highly nonlinear and the degree of saturation in the unbound layers of a roadconstruction depends to a large degree on the level of the water table.
