Wirtgen Group presents for the first time a completely electric process chain for road construction. The Vögele paver lays the asphalt, the Hamm compaction roller follows directly behind. Both machines operate without a diesel engine. The step marks a turning point for an industry that has so far relied almost exclusively on conventional drives.
Integrated solution instead of individual machines
The special feature does not lie in the mere electrification of individual devices. Wirtgen offers a coordinated system: paver and roller communicate with each other, energy supply is synchronized, work processes are coordinated. This distinguishes the approach from previous prototypes where manufacturers merely equipped individual machines with batteries.
For the site manager, this means: no diesel emissions, no engine noise, no fuel transport to the construction site. Especially in city centers and emission-protected zones, this becomes a decisive advantage. Initial pilot projects show that residents file significantly fewer complaints when construction is done electrically at night. For municipalities with strict noise protection regulations, this could open new time windows.
Technical challenges in road construction
Road construction specialists know: An asphalt paver needs constant power for hours. The Vögele paver must pull evenly on uneven ground, the screed must remain at constant temperature, hydraulic systems require continuous pressure. All of this costs energy. Previous diesel pavers deliver between 100 and 200 kW, depending on installation width and material.
The electric version must draw this power from batteries. Wirtgen has so far remained silent on specific capacities and ranges. Industry experts estimate: for an average working day of 6 to 8 hours, batteries in the range of 300 to 500 kWh would be needed. This is approximately three times that of an electric truck. Weight increases accordingly, as do costs.
Compaction without vibration motor
The Hamm roller faces similar problems. A tandem roller in road construction typically operates at 5 to 10 tons of operating weight. The vibration drum generates between 30 and 50 Hz frequency, the hydraulic drives provide continuous feed. The diesel engine provides 50 to 80 kW for this.
Electric operation becomes demanding: the vibration drive must remain precisely controllable, the battery must not collapse under load, the power electronics must withstand temperature fluctuations. Hamm has gathered years of experience with hybrid rollers, such as the HD+ CompactLine. This preparatory work pays off now. Control technology is proven, energy management systems are known.
Battery range: The critical point
Unlike Volvo CE, which provides concrete figures for their electric articulated dump trucks, Wirtgen Group remains tight-lipped. There are reasons for this: road construction is extremely heterogeneous. An expressway wearing course with 4 m installation width at 20 cm layer thickness poses different requirements than a municipal road with 2.5 m width and 4 cm wear layer.
Charging infrastructure will be crucial. Those who only install for 4 hours daily can recharge during lunch breaks and after work. Those working in three-shift operations need fast chargers with 150 kW or more. For highway renovations with full closures, this is currently barely feasible. For urban construction sites with short sections, it's much more viable.
Total Cost of Ownership: Is it worthwhile?
Investment costs will be significantly higher than diesel machines. Industry insiders estimate a 30 to 40 percent premium. A conventional 10-ton class paver costs approximately 350,000 to 450,000 euros. Electric would be 450,000 to 630,000 euros. An 8-ton tandem roller costs 120,000 to 150,000 euros, electric 160,000 to 210,000 euros.
This is offset by savings: no diesel means no fuel costs. For a paver consuming 30 to 40 liters per hour, over 1,000 operating hours annually that's approximately 50,000 to 65,000 euros. The roller consumes 15 to 20 liters per hour, amounting to around 25,000 to 30,000 euros annually. Electricity costs significantly less, even at construction site rates.
Maintenance costs also decrease: no oil changes, no diesel particulate filters, no SCR systems. The mechanics remain, as do hydraulics and wear parts. But the engine is eliminated. Experts estimate: 20 to 30 percent lower maintenance costs are realistic. Amortization still takes 5 to 7 years, depending on utilization.
What does this mean for the industry?
Wirtgen Group is not the only provider working on electric road construction machines. BOMAG is already testing electric rollers, Ammann is also showing electric compactors at bauma 2025. But the integrated solution of paver and roller is new. It shows where development is heading: from individual machines to integrated electric systems.
For construction companies, this means: whoever invests in new road construction fleets now should at least examine the electric option. Not for every application, not for every construction site. But for urban projects, for night operations, for emission-protected areas, electric drive becomes the standard. The technology is there, regulations are becoming stricter, funding is available.
Next steps and availability
Wirtgen has not announced series production yet. The presentation of the machines marks the development status, not market maturity. Pilot projects with selected construction companies are already underway. First field data is expected in the coming months. Actual market introduction is likely to occur in 2026 or 2027.
For fleet managers, this means: planning certainty doesn't exist yet. Whoever orders new machines in 2025 must continue with diesel. Whoever buys in 2026 or later should seriously calculate the electric option. The electrification of construction sites is progressing in large strides. Road construction is now part of it.
Comparison to other electric construction machines
Unlike electric excavators, where manufacturers like Liebherr and Volvo CE already deliver series machines, electric road construction is more complex. The machines must work synchronously, energy supply must be mobile, the work process must not be interrupted. Kleemann demonstrates with its fully electric crushing systems that stationary processes are also electrifiable. Road construction is the next level.
The Wirtgen Group thus sends a clear signal: electrification is no longer a niche topic. It is reaching the core of road construction. Whoever wants to remain competitive in 10 years must lay the groundwork today. The technology is available, costs are falling, regulations are becoming stricter. Change is unstoppable.
