A compaction test was performed on a soil sample from a proposed cut area. The maximum dry unit weight and optimum moisture content were determined to be 104.8 lb/ft3 and 20.7% respectively. What is the possible type or classification of soil for this sample?

In the construction of a road, the compaction specification required was 95% of Proctor maximum dry density at field moisture content within 2% of the optimum moisture content. The maximum dry density and optimum moisture content obtained in the laboratory from the Standard Proctor test were 1.94 gm/cc and 13.5% respectively. A site engineer conducted sand cone test at two locations and obtained the following results. Location No. 1 2 Mass of soil removed (gm) Wet 43.86 37.38 Dry 38.46 32.21 Mass of sand used (gm) 39.51 32.39 The density of sand used was 1.87 gm/cc. Check whether the specification was satisfied or not.

A compaction test was conducted in a soils laboratory using the Standard Proctor Method B test procedure. The weight of the compact soil specimen plus mold and baseplate was determined to be 3841 g. The volume and mass of the mold were 943.7 cm³ and 2066.0 g, respectively. A moisture content test was carried out on a representative portion of the sample and the results were 9.8%. Required Determine the dry unit weight in metric units, to the nearest 100th. Your Answer:
