Recycled asphalt shingles (RAS) often containing more than 20 percent asphalt binder has become another black gold in the asphalt industry. There are two basic types of RAS scraps in the market: tear-off asphalt shingles (TOAS) and manufacture waste asphalt shingles (MWAS). Both TOAS and MWAS have been used in hot-mix asphalt (HMA) paving in Texas.

Asphalt for paving goes through a mixing process in either a drum mix plant, which is a large-output and continuously operating facility, or a batch plant, which is a smaller-output plant that mixes in batches. Getting the Right Asphalt Mix. There are a few different ways to mix asphalt, the most popular of which are hot and cold.

Hot mix asphalt paving materials can be manufactured by: (1) batch mix plants, (2) continuous mix (mix outside dryer drum) plants, (3) parallel flow drum mix plants, and (4) counterflow drum mix plants. This order of listing generally reflects the chronological order of development and use within the HMA industry.

Hot Mix asphalt plant comes to use for the development of roadways, airplane terminals, dams and more. The control system of Hot Mix Asphalt plant comes with an easy to understand interface, enhanced production data administration, query and different capacities.

The process flow of any asphalt plant will depend on the type of the plant. Right now we have different types of asphalt mixer available in the market. These mixers are build keeping in mind different customer types. There are two major types / categories: batch type and continuous type. Batch type: With this design the production of hot mix will be done in batches of specific sizes

asphalt. A number of variations of both batch and continuous drum mixing plants have been Figure 1 Diagram of a typical batch plant The mixing process for incorporating RAP into asphalt mixes in batch mixing plants involves heat.
