Question

2) The standard mold is 4 inches in diameter and 4.584 inches tall, producing a volume of 0.03333 ft3. The energy per unit volume is 3Layers 5.5 Pounds 25 Laver3 Layers5.5 Polonds 1 foo) (0.03333 j) 12,375bf- ASTM says that if the soil is 1/4" over the top of the mold or anywhere below the top of the mold, the sample should be discarded. In the equation above, nothing would change in the numerator. Determine the actual energies if the soil is 1/4" above the top of the mold and 1/4" below the top of the mold. Which situation produces the highest energy? Which situation produces the greatest dry unit weight? How would that affect the shape of your curve?
