In most cases, the dryer capacity will determine the plant output. Other considerations

include ability of laydown crew to handle anticipated tonnage, number of haul units available,

distance of haul, dryer capacity, and screening capability of the gradation unit.

To determine the plant output, the percentage of dried aggregate that will be used in the

total mix must be determined. If no mineral filler is added at the fines feeder, the percentage of

bitumen subtracted from 100% will give the percent of dried aggregate.

Example: Percent bitumen 6.0%

Therefore: Percent aggregate = 100 - 6 = 94% dried aggregate

total mix

If mineral filer is added after drying, subtract the percent bitumen from 100% to get the

percent of total aggregate. Subtract the percent of mineral filler (expressed as a percent of total

aggregate) from 100%. Multiply the two results to obtain the percent of dried aggregate in the

total mix.
