New supply partnership targets durability, safety and carbon savings
Heidelberg Materials UK has secured a 12‑month framework with North Yorkshire Highways to provide approximately 35,000 tonnes of asphalt for maintenance and improvement schemes across the county, according to industry reports published on 14 July 2026. The agreement follows a competitive tender process and establishes a fresh supply link for the region’s road network.
The first scheme delivered under the arrangement was the resurfacing of Pateley Bridge High Street, where the company deployed a lower‑carbon mix incorporating its CarbonLock biogenic asphalt, matched with locally sourced stone from Coldstones Quarry. The asphalt was produced at Heidelberg’s Pateley Bridge plant, located only a few miles from the site, minimising haulage and supporting the local supply chain.
Technical approach to a challenging heritage streetscape
Engineers faced a tricky set of conditions on the steep high street, including sections with underlying cobbles and the need to preserve traction on gradients. To address this, Heidelberg Materials used a Tufflex stress‑absorbing membrane interlayer in the binder course to resist reflective cracking, while the surface course included aggregates with a polished stone value of 68 to meet skid resistance requirements.
Works were carried out overnight to limit disruption to residents and businesses. With the company’s Pateley Bridge plant situated within an Area of Outstanding Natural Beauty, approval was obtained from North Yorkshire Council to operate outside usual permitted hours for the job, avoiding a longer haul from the firm’s Leeds facility. This approach reduced vehicle movements, shortened delivery routes and enabled the use of nearby materials, aligning with the project’s sustainability objectives.
What the framework means for North Yorkshire
While the authority has not published a site list for the remainder of the 12‑month term, the scale of the framework indicates a steady pipeline of resurfacing and patching schemes across the county’s extensive network. Using asphalt manufactured close to worksites can help:
- cut HGV miles and associated emissions;
- improve programme reliability by shortening supply chains;
- support local quarries and plant operations through predictable demand.
For communities, the emphasis on overnight operations where feasible should reduce daytime traffic management and ease access for traders in town centres. The use of higher skid‑resistant surfacing is particularly relevant on rural and hillside locations common in the Dales and Moors, where winter conditions can be severe.
Lower‑carbon materials and local sourcing
The Pateley Bridge scheme showcased the supplier’s CarbonLock biogenic asphalt, designed to lock in biogenic carbon within the binder, alongside aggregates drawn from Coldstones Quarry. Locally produced asphalt from the nearby plant also lessens the need for cross‑county deliveries, which can be constrained by weather or peak‑season tourism traffic on narrow routes.
According to the company’s account of the project, selecting the Pateley Bridge plant over a site 29 miles away further reduced logistics impacts. The combination of a stress‑absorbing interlayer and high‑PSV surface course is intended to extend pavement life and maintain grip, particularly on steep sections where braking and turning forces are highest.

What residents should expect next
As the framework rolls out, further sites are likely to be scheduled on a rolling basis. Residents can typically expect advance notice of traffic management, with night‑time working where practicable to keep daytime access open. Where lower‑carbon materials and short supply routes are adopted, schemes may benefit from faster turnaround times and reduced construction traffic.
The framework underlines the council and contractor’s push toward more durable, safety‑focused surfacing while curbing emissions through local manufacture and shorter haul distances. For a county with thousands of miles of rural roads and market‑town streets, the combination of engineering detail and sustainability may set the template for upcoming seasons of maintenance.
