  • ASPHALT MIXING PLANTS AAPA Q

    Plant recycling of asphalt may be by using either hot or cold processes. A detailed account of all asphalt recycling methods may be found in the Austroads Guide to Asphalt Recycling (1997). Insitu recycling of asphalt is also referred to in a separate topic. The mixing process for incorporating RAP into asphalt mixes in batch mixing plants involves heat transfer from superheated aggregates

  • Asphalt manufacturing

    Asphalt plants typically produce asphalt, macadam and other forms of coated road-stone by mixing aggregate (crushed stones, gravel and sand) with bitumen. Asphalt is usually mixed in either a drum-mix plant, which operate continuously and generally have a large-output, or a batch-mix plant, which has a smaller output. There are two main production types, hot-mix and cold-mix. Many asphalt
