Hot Recycling
Smarter reuse of asphalt. Proven gains in performance and emissions.
Hot recycling reprocesses reclaimed asphalt at elevated temperatures, reducing raw material demand, conserving bitumen, and enabling high-performance asphalt mixes.
Advanced plant technologies support high RAP contents with optimised energy use and lower CO₂e emissions — helping drive more sustainable asphalt production across Europe.
At ART2025, we explored these key topics:

Recycling systems in an asphalt mixing plant – overview
Gain sound insights into the recycling systems of asphalt mixing plants. Learn about the recycled material content, emissions and financial savings that can be achieved with effective recycling.
-
An overview of recycling technologies: from dosing into the drum and dosing into the mixer to hot recycling systems.
-
Process-related considerations: process optimisation for higher recycled material content and optimum quality of the new asphalt.
-
Plug & Work: benefit from technologies that are suitable for new plants as well as for retrofit solutions on existing plants.
-
Digital support tools: recipe generator for maximising recycled material content.
Recycling management for hot mix asphalt
Production system solutions: analyse the entire value chain – from asphalt removal and processing to reuse in the asphalt mixing plant, with consideration of all relevant interfaces in order to maximise efficiency and sustainability.
-
Presentation of the system.
-
Our system enables the production of high quality asphalt with a high content of recycled material – a combination that has no contradictions.
-
Advantages of the production system.
-
Example from practical application – every % counts.
Foam bitumen with RAP systems
Temperature-reduced asphalt with high recycled material content – does that work?
-
Process-based consideration and feasibility: analysis of the efficiency and of the challenges related to the use of foam bitumen in combination with a high recycled material content.
-
Limits of foam bitumen: identification of the limitations and challenges in application.
-
Plug & Work: integration of foam bitumen systems into existing plants in combination with recycling processes.
REVOC system – the catalyst in asphalt production
As an add-on technology for existing plants to protect the existing equipment, thanks to the reduction of VOC values below 50 mg/m³.
-
Adaptation to existing plants with installed recycling systems.
-
Perfect retrofit solution.
-
Reduction of the total carbon (VOC) emissions by 50 %.
-
Increase of the recycled material content possible while adhering to the emissions limits.
Reducing the CO₂e footprint by up to 32 % with 90 % RAP in the complete road construction cycle
Maximum recycling, maximum profit – thanks to sustainable technologies on an asphalt mixing plant.
-
Sustainable circular economy.
-
Protection of resources and economic efficiency.
-
Compliance with emissions limits.
-
High RAP content as a key lever for CO₂e reduction.
-
90 % RAP enables up to 32 % CO₂e savings in the asphalt production process.
-
With the additional use of green hydrogen as a burner fuel, CO2e savings in asphalt production can be increased to up to 72% with 90% RAP.
