A measure of density of compacted fills as part of the specification requirement was performed by digging a hole in the soil, weighing the extracted soil and measuring the volume of the hole. The soil (moist) weighed 900 grams, and the volume of hole was 420 cu.cm. After drying the sample weighed 770 grams. Of the dried soil, 410 grams was poured into a vessel in a very loose state. Its volume was subsequently determined to be 280 cm3 . The same 410 grams of dried soil was then vibrated and tamped to a volume of 220 cm3 . If the sp.gr.of the soil sample is 2.70. a. Compute the void ratio of soil in situ state. b. Compute the void ratio in the densest state. c. Compute the relative density of the soil.
