Eurovia Surfacing has trialled the new Dynapac SD25 80C e fully electric highway-class asphalt paver, following its deployment during an overnight highway operation in Essex.
The Dynapac SD25 80C e completed a two-layer overnight surfacing operation in Essex without recharging and with 57% battery capacity remaining.
Undertaken in collaboration with Dynapac and SMT GB, the trial evaluated the machine’s endurance, performance and compatibility with an established highway surfacing operation.
Deployed on an Essex Highways resurfacing scheme on the A128 Tilbury Road in Brentwood, the paver installed 240.32 tonnes of asphalt across the binder and surface courses without requiring additional charging.
Binder-course paving began at 22:05, with the machine installing 139.58 tonnes of AC 20 HDM Binder Course 40/60 Tempera warm-mix asphalt. It then installed 100.74 tonnes of Fibrovia 10 Surface Course PMB 68 PSV, completing the final load at 01:08. Having heated its electrically powered screed and installed both asphalt layers, the machine completed the operation with 57% battery capacity remaining.
Powered by a 294 kWh battery, the SD25 80C e delivers up to 235 kW through five electric motors. It can operate for up to 10 hours on a single charge and can lay more than 1,000 tonnes of asphalt during a shift.
Paul Goosey, Managing Director at Eurovia Surfacing, said:
“The transition to lower-carbon construction is one of the most important opportunities facing our industry, and trials such as this help us understand how emerging technologies can support that journey. While the environmental and operational benefits of electric plant are clear, these machines currently require significantly greater upfront investment than conventional diesel-powered equipment. Understanding charging infrastructure, utilisation and whole-life costs will therefore remain critical as we evaluate future fleet-investment decisions.
“Our Environmental Roadmap sets out ambitious targets to reduce carbon emissions, increase operational efficiency and accelerate the adoption of more sustainable technologies across our business. The findings from this trial will help shape our future investment strategy and provide valuable insight into how electric plant can work alongside warm-mix asphalt, higher recycled-content materials and other lower-carbon construction techniques.”
Andy Bullock, Director Road Equipment, SMT GB said:
“The Dynapac ZERA SD25e paver represents significant developments for the paving industry. The ability to pave with zero emissions, considerably lower noise levels and lower operating costs, while maintaining the productivity and quality expected from a conventional paver, will allow contractors such as Eurovia to set new levels of project delivery standards and safety. The Eurovia teams experience and professionalism during these trials has allowed SMT and Dynapac to prove both the capability and suitability here in the UK.”
