A climate-neutral infrastructure by 2030

In the CIRCUROAD programme, companies, governments, and knowledge institutes collaborate to develop circular, bio-based asphalt. We aim to replace bitumen, the fossil-based binding agent in asphalt, with one derived from bio-based and circular raw materials such as by-products from forestry, the paper industry, and agriculture.

The consortium, hosted by Rijkswaterstaat, identifies the most promising solutions, ensures thorough validation, jointly manages risks, and promotes the market introduction of fossil-free asphalt. This approach helps reduce CO₂ emissions and minimizes dependence on fossil resources.

CIRCUROAD seeks to achieve maximum sustainable impact in the field of fossil-free asphalt. We follow a growth model designed to minimize risks and costs for road operators. Our goal is to begin with at least 30% bio-based and circular raw materials by 2030, progressively moving towards 100% fossil-free asphalt by 2050.

In doing so, we focus not only on technological innovations but also on building a reliable supply chain capable of delivering various types of sustainable asphalt, made from renewable raw materials, for widespread use by road authorities.
