en.Wedoany.com Reported - Heidelberg Materials UK has supplied 430 tonnes of low-carbon asphalt for the resurfacing of a 1.2-kilometre section of the Padiham Greenway cycle route near Burnley, Lancashire.

The greenway, built along the former Burnley to Padiham railway line, primarily serves cyclists and pedestrians as a link between Padiham, surrounding villages, and Burnley town centre, and is part of the National Cycle Network. The renovation was funded by National Highways.

The project was carried out by contractor BDS Yorkshire on behalf of the Walk Wheel Cycle Trust, which is responsible for maintaining the route. To meet sustainability goals, Heidelberg Materials recommended its CarbonLock bio-based bitumen and sourced local aggregates from Coldstones Quarry in Pateley Bridge.

Compared to standard hot-mix asphalt, the solution reduced the project's carbon footprint by at least 25%, saving 5.6 tonnes of CO₂ over the 1.2-kilometre stretch. The use of local materials also further reduced transport emissions.

Construction was coordinated with bridge repairs on the River Calder, thereby shortening the overall closure period and allowing the route to reopen more quickly.

The binder in CarbonLock asphalt contains bio-based materials that absorb and store CO₂ from the atmosphere during their lifecycle. This CO₂ is permanently "locked" into the asphalt, reducing its carbon footprint even during recycling after the road's service life ends.

James Playford, Regional Director of Asphalt at Heidelberg Materials UK, stated that as a key supplier to BDS Yorkshire in the northern region, they provided a low-carbon solution without compromising performance, and praised the client's collaboration as crucial to the project's delivery.

Matt Cragg, Senior Quantity Surveyor and Project Manager at BDS Yorkshire, expressed satisfaction with the quality and overall appearance of the final product, noting that clear communication and efficient problem-solving, along with Heidelberg Materials' close cooperation, were key factors in the project's success.
