This new way enables the use of higher proportions of RAP material in future asphalt mixes, which leads to significant financial and energy savings, and guarantees the production of high quality asphalt. The process is performed in three phases: separation – screening – compacting.
The RAP is separated through the use of a modified Vertical Shaft Impactor. The obtained material is then screened in order to redirect the coarse aggregates into piles according to their size. On the other hand, the fine material including the bitumen is sent to a compacting unit in order to form briquettes.
The bitumen briquettes obtained through AmoPepper’s compacting process include a significant number of advantages.
The briquettes’ format makes them incredibly easy to store and transport, meaning one AmoPepper plant can supply several asphalt plants. These briquettes also have a considerably low moisture content, and their quality can easily be tested and confirmed. Furthermore, they can be inserted directly into the mixer without having to change the production parameters.
AmoPepper brings solutions to a number of known issues associated to handling RAP.
Manufacturers no longer need to re-heat RAP material in order to produce new asphalt, and they can now use higher proportions of recycled material in their recipes than what was previously possible. Thanks to AmoPepper, they now have a clear understanding of the quality and composition of the RAP material they are using in their asphalt mixes.
