Problem 1: An embankment with a total volume of 20,000 cu.m. is to be constructed as part of a highway project. The soil to be used in the embankment will come from a borrow pit where the average moist unit weight and water content of the soil is 17.6 KN/m³ and 12% respectively. Assuming that the soil will be compacted to a dry density of 18.2 KN/m² at a moisture content of 15%. 1. Compute the weight of the dry soil required. 2. Compute the volume of the borrow required. 3. Compute the total quantity of water in liters that must be added to the fill during compaction to bring about a desired final moisture content of 15%.
