Ammann is offering several plant solutions for the use of RAP in the feed for asphalt production. Versatility and adaptability are claimed, along with high output and consistent mix quality and the firm has different plants to suit the needs of different customers.
The firm’s ACC Alpine mixing plant is said to enable producers to maximise RAP content but without sacrificing mix quality. This plant is available with a range of options to suit the specific needs of different users. Typical RAP rates reach 50% as standard and up to 60% with the addition of a dual-collar feed. An extended drum-mixing section is used that helps to optimise heat transfer and mixing time, delivering consistent, high-quality mix designs at market-leading RAP levels.
Meanwhile, the Ammann high-recycling technology (HRT) asphalt batch plant is engineered to operate efficiently with very high RAP content, even up to 100%. A key feature of the HRT plant is the vertical introduction of heated RAP into the mixer. This configuration ensures optimal heat transfer, excellent mixing quality and full protection of the aged binder. As with other plants in the range, the HRT is available with an array of options to meet the needs of the customer and the application.
Both plants are fitted with the firm’s as1 Control System which improves mix quality while reducing material waste and energy consumption.
The plants are also available with Amman’s sophisticated Plant Guard system which uses the Condition Monitoring module and connects to the Ammann as1 Control System. This is linked to sensors across the plant with real-time and historical KPIs shown through intuitive dashboards. The Maintenance Manager 4.0 module optimises plant care and includes guides on how to perform maintenance. Dashboards provide insights about plant-maintenance performance, while the platform includes an online catalogue for spare parts with full shop functionality.
