Low Carbon Asphalt Solutions


Engineered solutions to driving low carbon, durable and more sustainable roads


Why Cutting Carbon in Roads Matters

The UK’s road network is vital to economic growth, connectivity, and everyday life—but it’s also a source of carbon emissions. With the construction and maintenance of roads contributing significantly to the built environment’s carbon footprint, the need for sustainable, low-carbon solutions has never been more urgent. Tarmac is leading the charge with CEVO, a pioneering range of low carbon asphalt and PAVE solutions designed to help clients meet their Net Zero goals without offsetting or compromising performance or durability.

Introducing CEVO - The Future of Sustainable Asphalt


Building on the success of Tarmac’s CEVO low carbon concrete, the CEVO asphalt range brings together cutting-edge materials technology and sustainable construction practices to dramatically reduce carbon emissions across the entire road lifecycle.

What Are Bio Binders and How Do They Work?

Bio binders are plant-based alternatives to traditional petroleum-derived bitumen. Sourced from renewable materials such as lignin or vegetable oils, they offer a dual benefit:

Lower embodied carbon due to their biogenic origin.

Carbon sequestration, as they can trap and store COâ‚‚ within the asphalt matrix.

In trials, bio binders have shown excellent compatibility with RAP and warm mix technologies, making them a cornerstone of CEVO’s low carbon performance.

Packed products
for reinstatement

Tarmac's packed highways are paving the way toward a more sustainable future with innovative use of bio-based materials. Our ULTIPATCH POTHOLE and ULTIPATCH FOOTWAY incorporate a cutting-edge binder made from renewable plant sources, reducing reliance on traditional fossil-based bitumen. Not only do they lower carbon emissions during production, but they also deliver the same strength, durability, and performance expected from reinstatement repairs.

Tarmac’s Proven Capability: Paving Excellence in Action



CEVO Asphalt
A64
UK’s Lowest Carbon Resurfacing Trial

On the A64 near Bramham, Tarmac delivered a 75% reduction in carbon emissions without relying on offsetting. A stretch of 150m also achieved Net Zero – incorporating ACLA aggregates to demonstrate another step forward in the Art of the Possible today.

The project used
37% RAP in base layers and 20% in surface course

Warm mix asphalt

Shell’s biogenic binder, locking carbon into the pavement

Electric and hybrid plant, including rollers and bond coat sprayers
The result

A smoother, more durable surface with an IRI improvement from 2.0 to 0.9, setting a new benchmark for sustainable road construction.
