A 16-foot wide, 10-inch thick concrete pavement is to be slipformed using 9-cy batches mixed at a central-mix plant. Each batch is mixed for an average of 3 min and the plant is 75% efficient. Paver production matches plant production. Paver production is 80% efficient. Truck cycle time is 30 min. What is the plant production in cubic yards per hour? (See example 15.5 in the book.)
