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.

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, aggregates are blended with bitumen, filler, and additives under controlled temperature.
Storage & load-out Finished asphalt is transferred to insulated silos or directly to trucks for paving.

Sustainability in Action
Recycling integration (RAP)
Ammann plants are engineered to incorporate high percentages of recycled asphalt into new mixes, reducing the need for virgin materials and supporting circular economy goals.
Energy savings
Counterflow drying, 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 Burner Technology supports a wide range of sustainable fuels, including hydrogen, bio-oil, LPG, and other CO₂-neutral options, enabling flexible and future-ready plant operation.
