In a field density test, using the oil method, the wet mass of sod removed from a small hole in the fill was I SO kg. The macs of nil (sp. gr. 0.90) required to fill the hole was 0.81 kg, and the field water content was found to be 25% If the p, of the sod solids is 2700 kg/m', what is the dry density and degree of saturation of the fill?
