The excavated material has a wet unit weight of 1,510 kg/ cu metre and a dry unit weight of 1,398 cu metre. The material will be used to build an embankment. According to specification, the dry unit weight of the compacted material should be 1,826 kg/ cu metre, with a water content of 12%. The net section of the embankment is 86,000 cu metre. What is the moisture content of the excavated soil? How many cu metre of excavation will be required to construct the embankment? Do we need to add water or not? If yes, what’s the volume of added water?
