Recycled Asphalt Pavement (RAP) material can be recycled with our asphalt recycling systems. Not only will this ensure your role in the conservation of our natural resources, but it will also lower your production costs by using less raw materials, such as bitumen and aggregates. The asphalt recycling system allows the virgin asphalt plant to recycle RAP material by mixing it together with virgin aggregates for the hot mix asphalt. RAP material is gathered from excavation of road pavement or milling waste, which is then pulverised by an asphalt recycling granulator, processed and screened into different sizes required, before being mixed with the virgin aggregates. Excavated chunks of asphalt pavement would need to be crushed with an asphalt granulator to ensure that the original grain size of aggregate is maintained, and excessive fines or asphalt dust are reduced. Up to 60% RAP material can be recycled with HRC. RAP material is heated with hot air from a hot air generator in a parallel recycling drum. The heated RAP material is then weighed before being mixed with virgin materials in the mixer of the asphalt mixing plant.

Our unique Screen Drum System combines the drying and screening processes of aggregates in one drum. The aggregates move through the drying drum in counterflow method. The heated aggregates drop through the slots onto the screens on the outer side of the drum. Carried by the rotation of the drum and the spiralling flights, the heated aggregates then pass through the screens into the respective hot bin without losing any heat radiated from the drum.  This results in lesser operating costs from reduced fuel consumption and maintenance costs due to the elimination of hot elevator and vibrating screens. There is no more maintenance needed from the high wear-and-tear parts of the hot elevator, plus, without hot elevator, route of dried aggregates is shortened, and unnecessary heat dissipations are eliminated. The proximity of Screen Drum to the Hot Mineral Bins ensures the maximum heat retention to the aggregates.
