RARx is a high-performance asphalt additive made from recycled end-of-life tyre rubber, designed to improve road durability, reduce maintenance and support circular economy infrastructure. We are actively looking to partner with forward-thinking companies, investors and recyclers to scale this solution across the UK and internationally, building a new standard for sustainable roads.
RARx (Recycled Asphalt Rubber eXtender) is an asphalt additive based on recycled tyre rubber, developed to improve the performance of asphalt mixtures while creating a higher-value use for end-of-life tyres. It supports greater durability, stronger resistance to cracking and deformation, and lower traffic noise compared with conventional road mixtures.
RARx supports a more circular model by turning recycled tyre rubber into a valuable road construction material, creating environmental and commercial value from waste streams.
The value of RARx is not just sustainability. It is also about delivering more resilient asphalt mixtures with a stronger long-term infrastructure proposition.
RARx is an asphalt additive based on recycled tyre rubber, designed to improve asphalt mixture performance while helping create a higher-value route for end-of-life tyre recycling. Its value comes from combining durability, sustainability and simpler deployment into one solution.
Improved durability can help roads last longer and reduce maintenance intervention costs over time.
Supports a more sustainable road solution with the potential for lower material consumption, lower energy use and recycled-content value.
Can contribute to higher surface grip and lower water spray, supporting safer driving conditions.
Contributes to quieter road performance compared with conventional mixtures.
Designed for consistent performance from plant to site, reducing handling risk, delays and material waste.
Works within familiar asphalt processes, helping producers and contractors adopt innovation with less disruption.
Better handling stability can help reduce rejected material, wasted loads and avoidable operational disruption on road projects.
Easier usability can make adoption more attractive for asphalt producers, contractors and large materials groups looking for practical innovation.
One of the strongest commercial advantages of RARx is practical adoption. It is designed to work within existing asphalt production and laying processes, helping contractors and asphalt plants integrate the product with minimal disruption. This supports a smoother plant-to-road operation, lower handling risk and more consistent delivery.
RARx can be integrated into existing asphalt production processes without requiring plant upgrades or major operational changes, making adoption simple for contractors and asphalt producers.
Compared with more complex modified bitumen systems, RARx supports easier handling, potentially lower temperature requirements and reduced equipment dependency, improving efficiency from plant to site.
Beyond sustainability and performance, RARx is designed to support a stronger economic case for road owners, contractors and recycling partners by improving pavement life, reducing maintenance needs and creating a higher-value use for recycled tyre rubber.
If road surfaces last longer and require fewer interventions, the total cost across the asset lifecycle can be reduced, even where initial material costs differ from conventional solutions.
RARx creates an opportunity for rubber recyclers to move from commodity output into a more differentiated, higher-margin infrastructure product.
Our aim is to work with recycling companies, industrial partners and investors who want to move up the value chain by manufacturing RARx locally and supplying a differentiated product into the road and infrastructure market in the UK and beyond.
Partner with recycling companies that already handle end-of-life tyre processing and crumb rubber production.
Establish a dedicated factory to produce the RARx additive at commercial scale.
Provide a higher-value product to asphalt plants, contractors, councils and infrastructure programmes.
Turn a recycling operation into a premium construction materials business with stronger margins and strategic positioning.
RARx is more than a product. It is an opportunity to reshape how roads are built by combining performance, sustainability and circular economy value at scale.
Our goal is to expand beyond the UK and work with partners across international markets to bring RARx into large-scale infrastructure programmes.
We are looking to collaborate with companies and investors who share our vision: reducing waste, improving road safety, and building more sustainable infrastructure using recycled materials.
RARx enables partners to move up the value chain, transforming recycled tyre rubber into a premium construction product with strong commercial and environmental impact.
Together, we aim to create safer, quieter and longer-lasting roads while contributing to a more sustainable future.
We aim to position two complementary road solutions for different commercial and technical needs: RARx for performance-led asphalt applications and Chip Seal for more cost-sensitive surface treatment opportunities.
A higher-performance asphalt additive solution designed for roads where durability, sustainability, noise reduction and safety value are key priorities.
A more economical solution aimed at road surface treatment use cases where cost-efficiency and practical deployment are the main drivers.
