Unformatted text preview: d in borrow pit, 87.0pcf; w in borrow pit, 13.0%; G s , 2.7; Modified Proctor w opt , 14.0%; Modified Proctor d,max , 116.0pcf. Assume that 50,000 yd 3 of the soil from the borrow pit is to be delivered to an embankment at a construction site. By the time it reaches the site, the water content is 9%. It will be compacted to a minimum of 90% of the modified Proctor maximum dry density. Determine the total weight of water (in lbs) that must be added to the soil to increase the moisture content to the optimum water content. Answer: 5.9 x 10 6 lb of water. Problem 5: For a granular soil, given moist = 108 pcf, D r = 82%, w = 8%, and G s = 2.65. For this soil, if e min = 0.44, what would be the dry unit weight in the "loosest" state? Answer: d = 63 pcf...
