Problem 2 (26 points) Results from a standard Proctor compaction test yield an Optimum Moisture Content (OMC) of 12% and a maximum dry unit weight of 18.1 kN/m. Given this information, address the following questions. a) The soil was used to construct an embankment on a construction site. A sand cone test indicated that a layer of the compacted fill had a total unit weight of 19.8 kN/m3 and a moisture content of 11%. Specifications call for the...
