В Великобритании успешно завершены первые испытания полностью электрического асфальтоукладчика класса автодорог

Eurovia Surfacing has completed what it says is the first UK operational trial of a fully electric highway-class asphalt paver. The Dynapac SD25 80C e completed an overnight resurfacing shift on the A128 Tilbury Road in Brentwood, Essex. The battery-powered paver, supplied as a trial in collaboration with Dynapac and equipment dealer SMT GB, laid two asphalt courses without requiring a recharge. Eurovia reports the SD25 80C e installed 240.32 tonnes of material , 139.58t of warm-mix AC 20 HDM binder course, and 100.74 t of Fibrovia 10 PMB surface course. The work began at 22:05 and finished the final load at 01:08. The machine still had 57% of its battery capacity remaining at the end of the run. Technical details supplied by the manufacturers indicate the SD25 80C e is powered by a 294 kWh battery and drives five electric motors for a peak output of up to 235 kW. Dynapac’s specifications suggest the model can operate for up to 10 hours on a single charge and is capable of laying more than 1,000t of asphalt in a shift under suitable conditions. For contractors and asset owners the trial raises several operational considerations. Eurovia managing director, Paul Goosey, framed the exercise as part of the company’s evaluation of lower‑carbon plant and the practicalities of adopting electric equipment at scale. ” 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.” SMT GB director for road equipment Andy Bullock, described the SD25 e as delivering “zero emissions, considerably lower noise levels and lower operating costs” and paid tribute to the Eurovia team involved in the trial. “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.” Context for highway engineers and contractors - Emissions, noise and site safety: Electric pavers remove tailpipe emissions at the point of use and can substantially reduce site noise, which may aid night‑time working near residential areas and support compliance with local environmental limits. - Charging and logistics: A 294 kWh battery represents a significant energy store but scaling use across fleets may require planning for rapid recharging or battery‑swap strategies, grid capacity at depots or on‑site charging solutions for larger overnight operations. - Productivity and materials compatibility: Eurovia’s trial included both warm‑mix binder and a polymer‑modified surface course. Compatibility with electrically heated screeds and maintaining mat temperature are critical considerations for quality and compaction, the trial’s results indicate the SD25 e managed screed heating and layer installation within a typical overnight programme, although longer or more demanding schemes may need further assessment. - Whole‑life economics: Potentially higher upfront capital costs for electric plant need to be balanced against lower fuel costs, potential maintenance savings (fewer moving parts in electric drivetrains), reduced site mitigation for noise and emissions, and regulatory or client incentives for low‑carbon delivery. What remains to be tested The trial demonstrates feasibility on a single shift and a defined production volume. Further trials may now be used to confirm performance across a wider range of site conditions, longer shifts, variable ambient temperatures (which can affect battery performance), different asphalt mixes and continuous operations where recharging logistics are more challenging. Longitudinal data on reliability, maintenance requirements and total cost of ownership will be important for contractors making fleet replacement decisions. Eurovia has said the findings will feed into its Environmental Roadmap and future investment choices.
