The CHAPLIN programme for the development of 100% fossil-free asphalt is now known as CIRCUROAD. The Directorate-General for Public Works and Water Management in The Netherlands (Rijkswaterstaat) succeeds Circular Biobased Delta as lead partner of the programme, which works on bio-asphalt in which the oil product bitumen is replaced by a bio-based and/or circular binder.

The replacement requires innovative technologies in which CHAPLIN members have already achieved several successes. For example, there are dozens of experimental sections with different compositions and calculations show that a 75% CO2 reduction is already possible now. There are 136,000 kilometres of asphalt in the Netherlands alone, so the potential of this innovation is huge.

Sustainable Road Pavements

Rijkswaterstaat’s goal is to have a climate-neutral, energy-neutral and circular infrastructure by 2030. All materials will be highly reused and the use of primary raw materials will be halved. Ludo Hennissen, Programme Manager Sustainable Road Pavements at Rijkswaterstaat: “To achieve these goals, we have established the Sustainable Road Pavements transition path within Rijkswaterstaat. Within this theme, CHAPLIN is a programme within which we have been working constructively with the entire asphalt chain for years. It was the obvious choice to act as host after Circular Biobased Delta.”

The principle of open innovation will remain in place and the programme manager, Joop Groen, will also retain his position. “The focus will be even more demand-driven than now, so that our innovations are optimally aligned with market needs,” he says. “In this way, together we will accelerate the transition to fossil-free asphalt.”
