Title: ASPHALT PAVING MIXTURES--DRUM DRYER (DISCUSSION)
Accession Number: 00377903
Record Type: Component
Availability: Find a library where document is available Abstract: The dryer-drum mixing process can accommodate a wide range of asphalt mixtures, particulary regular hot-mix asphalt concrete. The system includes a cold feed unit for aggregate which goes directly to the drum at which point the asphalt is added. Blending and heating takes place in the drum and mixtures with temperatures ranging from 180 deg-300 deg F are produced. The asphalt is aged less than conventional plants and well-coated mixtures are readily compacted at low temperatures because of the moisture present. In addition, stack emission of dust is reduced considerably. (Author)
