Asphalt-Mixing Plants
An asphalt mixing plant dries, heats, and blends aggregates with liquid bitumen, mineral filler,
and -if needed - additives to produce asphalt mixes. These plants are the backbone of road
construction and rehabilitation, ensuring consistent quality and compliance with strict safety and
environmental standards.
Hot Mix Plants
Ammann Plant Values
Core process steps
Drying & heating. Aggregates pass through a high-efficiency counterflow dryer, where moisture is removed and
material is brought to the target temperature.Weighing & dosing. Load cells ensure precise measurement of each constituent, guaranteeing mix accuracy.
Mixing. In a pugmill mixer (batch plants) or a continuous drum mixer, aggregates are blended with
bitumen, filler, and additives.Storage & load-out. Final hot mix asphalt is discharged into insulated silos or directly to trucks for being transported to the final paving phase.
All Ammann plants are operated via the as1 Control System, which integrates real-time sensors and closed-loop feedback to optimise fuel and power consumption while ensuring consistent mix quality. Environmental modules—such as baghouse filters, Blue Smoke Treatment, Ammann Foam, and noise insulation—support compliance with the world’s most demanding air-quality regulations.
Sustainability in action
Recycling integration (RAP)
Ammann plants are engineered to incorporate high percentages of recycled asphalt (even up to 100%) into new mixes, reducing the need for virgin materials and supporting circular economy goals.
Energy savings
Counterflow drying, ADX technology, variable-frequency drives, and advanced automation combine to lower fuel consumption and optimize energy use, ensuring cost efficiency and environmental responsibility.
Emission control
High-efficiency baghouse filters capture more than 99.8 % of particulates. Additional odor and VOC-reduction systems keep production sites clean, compliant, and community-friendly.
Alternative fuels
Ammann burners support a wide range of sustainable fuels, including hydrogen, wood dust, bio-oil, LPG, and other CO₂-neutral options, enabling flexible and future-ready plant operation.
