The plain-words read of this example
The fill goes in 5 lifts of about 7.2 in, and each must reach 114.0 lb per cu ft dry, 95% of the 120.0 Proctor maximum. It is 3.0 points dry of optimum: add about 9,842 gal a lift, plus what evaporates. Plan 40 density tests, 8 a lift. Rolling takes 18.6 h with 6 passes, about 2.1 days, and costs $2,237.76. Prove the passes on a test strip before you commit the schedule.
