Stationary asphalt plant ABP HRT

discontinuousparallel-flowcounterflow

Short description
The ABP HRT by Ammann is a stationary batch asphalt-mixing plant engineered for high-recycling applications. HRT (High Recycling Technology) enables production with very high proportions of reclaimed asphalt pavement (RAP). An integrated RAP drying drum (RAH60 parallel-flow or RAH100 counterflow, with optional hot gas generator) is positioned above the mixer to optimise material flow and reduce wear and sticking in the recycling loop.

Key capabilities

• Production capacity range: 240 - 400 t/h
• Recycling rate: up to 100% RAP (High Recycling Technology)
• Plant type: Stationary batch plant with modular configuration

Technology and advantages
Ammann integrates intelligent automation for precise recipe control and consistent product quality, digital platforms for predictive maintenance and real-time monitoring, and burners compatible with low-emission alternative fuels. The plant supports warm-mix technologies, advanced emission control, noise reduction measures and modular add-ons for capacity or functionality expansion.

Design highlights

• Integrated RAP drying drum (RAH60 parallel-flow or RAH100 counterflow) directly above the mixer to optimise material flow.
• Options for hot gas generators and dryer drum / burner combinations matched to capacity.
• Modular, configurable layout enabling tailored capacities, control packages and retrofit solutions.

Highlights / Peak performance
The ABP HRT series delivers reliable outputs between 240 and 400 t/h for large-scale projects, allowing high RAP incorporation while maintaining mix quality and production consistency.
