You excavate 130,000 BCY. The shrinkage is 14%. After the soil is compacted into a fill, what will the compacted volume be?

How the mineralogical composition of true clay is distinctly different from the mineral components of the other soil types?

A specimen of clay has a water content of 82% and a saturation of 95%. The specific gravity of solids is 2.76. What is the void ratio of this soil? What is the moist density of this soil in kg/m3? Round the answers to five significant figures. Include phase diagram(s).

Question 1: Earth whose in situ weight is 112 pcf, whose loose weight is 95 pcf and whose compacted weight is 120 pcf is placed in a fill at the rate of 250 cy/hr, measured as compacted earth. The thickness of the compacted layers is 6 inch. A compactor with a roller drum width of 84 inch is used to compact the material at a speed of 3.5 mph. Assume a 55 min hour operating efficiency. Determine the number of rollers required to provide the necessary compaction rate if eight drum passes are specified for each layer of earth. O 1 Roller O 3 Rollers O O Roller O 2 Rollers
