A highly innovative asphalt paver prototype has been developed by Volvo CE, featuring electric power. The machine is based on the conventional P4820 and offers the same tamper bar screed (with a maximum width of 6.5m) and hopper dimensions as the standard machine. However, power comes from a battery allowing a running time of 6-9 hours, depending on the application. Recharging takes from 60-90 minutes, depending on the supply.
The firm says that the electric machine is more efficient than a diesel as it only uses power when in use, whereas a diesel will typically be idling while waiting for another tipper load of asphalt. The electric drive is also 95% efficient, unlike the lower efficiency of an internal combustion engine (typically around 35%).
The machine has been developed as part of Volvo CE’s drive towards new green construction technologies. However, with the rights to the ABG machines being transferred to Ammann it remains to be seen what will happen with the project. It is worth noting though that Ammann is also keen to introduce greener construction technologies.
