The natural bulk unit weight of a sandy stratum is 18.54 kN/m3 and it has a water content of 8%. For determining the density index, dried sand from the stratum was first filled loosely in a 300 cm3 mould and then vibrated to give a maximum density. The loose dry mass in the mould was 480 g and the dense dry mass at the maximum compaction was 570 g. If the specific gravity of solids is 2.66, find the density index of the sand in the stratum.
