b. Batch plant. Batch plants have also been modified so that recycled mixtures can be produced (fig 4-3). The
modification consists of adding a feeder and conveyor to carry the reclaimed asphalt pavement directly to the weigh
bucket. The new aggregate that passes through the dryer is usually superheated to between 500 and 600 degrees F so that
when the materials are blended, the resulting temperature is suitable for mixing and compaction. An increase in the amount
of reclaimed asphalt concrete used in the mix would require an increase in the new aggregate temperature. Also, additional
moisture in the new aggregate or reclaimed asphalt pavement stockpiles will require additional heat. Therefore, to save
energy both stockpiles should be kept as dry as possible,
