Latest eABG 4820 model makes its UK debut on flagship low-carbon A47 scheme for National Highways

A PROJECT to resurface a section of the A47 in East Anglia, using over 90% recycled materials, served as the ideal testing ground for an Ammann aABG 4820 electric paver. Making its UK debut on this essential low-carbon National Highways scheme, the electric paver exceeded the performance and battery-life expectations of the entire site team.

The project – resurfacing the route between Acle and Great Yarmouth using more than 90% recycled materials – provided an ideal proving ground for the next-generation electric paver. Delivered by Heidelberg Materials with design support from WSP, the scheme has produced a structural road layer made almost entirely from reclaimed asphalt, marking a significant step forward in sustainable road construction.

Chosen to meet the project’s ambitious environmental goals, the eABG 4820, claimed to be the largest electric paver currently on the market, combines high productivity with lower emissions. The machine can lay up to 1,200 tonnes per day while reducing CO₂ emissions by up to 70%, compared with diesel-powered equivalents.

Equipped with a Variomatic screed offering paving widths of up to 6.5m and output of up to 500 tonnes/h, the paver delivered consistent, high-quality results on site, with performance and battery life exceeding expectations.

Jake Giddings, site manager for Heidelberg Materials, expressed initial scepticism based on previous experiences with other brands but was quickly persuaded by the durability of the eABG 4820. ‘The Ammann paver performed to the same high standard as the diesel version, and the battery lasted longer than expected. We’d start a shift on 95% and finish on 40% charge.’

To further cut the project’s carbon footprint, Heidelberg Materials built a recycling plant near the site, reducing haul distances and associated emissions while also providing a convenient low-carbon charging hub for the paver. Transport was supported by hydrogen-powered low loaders, reinforcing the scheme’s sustainability credentials.

On the A47 scheme, performance gains extended beyond the paver, with an Ammann eARX 26-2 electric light tandem vibratory roller also delivering impressive results on site, showcasing its efficiency and reliability to the project team.
