NAPA has a document “Balancing Production Rates” IS-120 that offers a good breakdown of each of these operations. In addition, there are excel sheets and Apps that now simplify the calculations. Caterpillar Paving Products has developed a great app based on this and can be found here. A very basic excel sheet can also be accessed below.
