High Rap Aggregate Dryer with External Mixer

The Double Barrel XHR achieves a quality high RAP mix. To achieve this quality mix, it utilizes both a preconditioning chamber on the drum and an external mixer with the addition of the V-Pac™ Stack Temperature Control System to maintain as low an exhaust temperature as possible when running high RAP content. A stainless-steel drum and stainless-steel combustion flights withstand the higher temperatures associated with running high RAP. The Astec warm mix system comes standard on all Double Barrel XHR mixing systems.
