Swiss construction equipment manufacturer Ammann has partnered with Volvo Penta to develop the fully electric eABG 4820 asphalt paver, bringing battery-powered technology to demanding road construction applications.
Based on Ammann’s diesel-powered ABG 4820, the electric machine is designed to maintain conventional paving performance while eliminating direct emissions during operation.
270 kWh Battery and 150 kW Fast Charging
The eABG 4820 uses Volvo Penta’s 600-volt electric drivetrain, powered by three modular battery units with a combined capacity of 270 kWh.
Its permanent magnet synchronous motor delivers 99 kW of rated power. Charging is available through a CCS2 connection, supporting DC fast charging at up to 150 kW, with a claimed charging time of approximately 1.5 hours. AC charging is also supported at up to 22 kW, requiring around 12 hours.
Electric Paver Matches Heavy-Duty Performance
Ammann specifies a theoretical paving capacity of up to 500 tonnes of asphalt per hour. Depending on the screed configuration, paving width ranges from 2.5 to 6.5 metres, with a maximum paving thickness of 300 mm.
The machine weighs approximately 13.8 tonnes without the screed.
According to Ammann, the eABG 4820 has achieved a daily paving record of 1,200 tonnes for an electrically powered asphalt paver. The machine is already available for customer orders.
Lower Noise and Construction Emissions
Beyond eliminating direct operating emissions, the electric drivetrain reduces noise on construction sites, making the machine suitable for urban roads, cycle paths and projects near residential areas.
Ammann estimates that the electric paver can reduce CO2 emissions by approximately 70% compared with a conventional machine. Actual emissions savings depend partly on the electricity source used for charging.
Electric Road Construction Equipment Expands
Ammann’s development reflects a broader shift toward electrification in construction machinery. Dynapac has also introduced electric asphalt pavers, including the SD25 80C e, which features five electric motors producing a combined 235 kW and a 294 kWh battery.
The machine supports DC charging at up to 235 kW and is designed for operating periods of up to eight hours.
These developments demonstrate how battery-electric technology is expanding into energy-intensive road construction equipment, where reduced noise and local emissions could offer advantages for urban infrastructure projects.
