Title and Subtitle A SYNTHESIS OF WARM-MIX ASPHALT April ...

Hot-mix asphalt (HMA) is typically produced in either batch or drum mix plants at a discharge temperature ranging from 280°F to 325°F. It has been necessary to use these elevated temperatures to dry the aggregates, coat them with the asphalt binder, achieve the desired workability, and provide sufficient time to compact the HMA mat.
