Asphalt Recycling Plant

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.

Features

• Energy conservation by utilising parallel drum completed with a high-pressure burner and radial-/axial-flow fan coupled with a regular plate, ensuring a fully combusted flame.
• Pollutants reduction by expending harmful fumes and filtering uncirculated asphalt fumes at the baghouse filter.
• Optimum temperature of RAP material is controlled at the ideal temperature of 140-150 °C before being discharge into the buffer silo.
• Production of excessive asphalt fines or dust is reduced to avoid clogging at the pollution control unit, reduce maintenance at the plant’s circulation system and drum, and avoid changes of the properties of RAP materials.

With CRC, up to 30% RAP material can be utilised in the hot mix design. Direct from RAP hopper, the RAP material is weighed before being mixed with virgin materials in the mixer of the asphalt mixing plant.
