About Asphalt Recycling Technologies
Asphalt Recycling Technologies (ART) is an international platform dedicated to advancing innovation in asphalt recycling and sustainable road construction. Following the success of the inaugural convention in 2024 and the second successful event in 2025, ART has established itself as a key meeting point for industry leaders, researchers, and professionals to share knowledge, exchange ideas, and drive unified standards across the sector.
Our focus extends from the latest recycling technologies to environmental sustainability and practical applications in cold recycling, hot recycling, and bitumen-stabilised materials (BSM). Through conventions, workshops, and shared resources, ART offers unique opportunities to connect with experts, explore new solutions, and contribute to the global shift toward sustainable road infrastructure.
Together, we are shaping the future of asphalt recycling.
"ART provides a platform that will set the path towards promoting sustainable practices in road construction"
Previous event: ART2025
Explore the wealth of knowledge and materials from ART2025, held on 8–9 September 2025 in Aachen.
The convention brought together 250 participants and proved a resounding success. Insights shared by our speakers have set the course for the future of this platform and strengthened the global drive for more sustainable road pavement construction.

Key Topics
Hot Recycling
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.
