In a Proctor compaction test, the optimum water content of a fill material is found as 12%. Specific gravity of solids is 2.6, maximum void ratio is 0.93, and minimum void ratio is 0.53. A 2.4m (height) x 30m x 30m embankment of this soil is to be compacted to 90% relative density.

a)The embankment will be compacted in 8 layers of 30cm thickness.Calculate the quantity of water to be added to each layer for the most efficient compaction.

b)You notice one of your technicians made a mistake in determining the minimum void ratio, its correct value is 0.43. How much volume of additional soil (compared to the volume calculated with the incorrect emin) at its loosest state is needed to complete the embankment?

A compaction test measures a maximum dry density of 1666 kg/m3 and an optimum water content of 18.0%. The soil has an estimated Gs value of 2.68. A contract requires compaction to 95% of maximum dry density at water content of optimum or greater. A field test measures a moist density of 2023 kg/m3 and a water content of 27%. a)     Use the values given for measured moist density and water content, calculate the field dry density b)     Does the...

A field density test on compacted, well-graded sand produced the following information: water content = 5%, total density = 112 pcf. Additional standardized tests were performed for determining the sand's relative density following ASTM D4253 and D4254, and these standardized tests produced a minimum dry density of 89 pcf and a maximum dry density of 115 pcf. The specific gravity of solids is 2.65 for this soil.Compute (a) the field dry density and void ratio, (b) min and max void...
