Astec show model of relocateable asphalt plant
Astec has brought along a detailed model of a complete relocateable asphalt plant to explain the key features.
The plant incorporates double-barrel technology. A continuous process delivers virgin aggregates or 50% recycled material into the inner drum where it is dried. The aggregate then drops out to the outer drum, where bitumen is injected. Advantages include guaranteed mixing times and being able to heat the material within a single system.
The plant’s warm mix system uses foam rather than additives. Astec said foaming provides an enhanced coating as well as involving only a one-time cost.
