Swedish construction machinery manufacturer Wirtgen Group partner Dynapac is celebrating a technical premiere: With the first fully electric large asphalt paver for the European market, the company wants to electrify road construction. The market launch marks an important step in the electrification of the construction site – and poses the question to established manufacturers of how quickly they can catch up.
The new asphalt paver relies on battery operation instead of a diesel engine. This is technically challenging: road pavers require constantly high power for drive, screed unit and heating of the screed. In particular, the thermal conditioning of the mix and the screed is considered energy-intensive. According to Dynapac, the company has developed a battery system for the European variant that meets these requirements – however, the press release does not provide details on capacity and charging time.
For construction companies, electrification means a fundamental change: they must provide charging infrastructure on the construction site, plan operating hours differently, and recalculate Total Cost of Ownership (TCO). While the elimination of diesel, SCR systems and diesel particulate filters reduces maintenance costs, higher acquisition investments and still unknown battery lifespan make economic calculations complex. However, those who deploy machines in inner-city areas or in low-emission zones benefit from zero emissions at the site of use – an advantage that will become increasingly important from a regulatory perspective.
The competition is watching the introduction closely. While manufacturers like Joseph Vögele and BOMAG have so far focused primarily on hybrid drives and efficiency optimization for diesel engines, Dynapac is penetrating the market with a full-electric solution. This increases pressure on established suppliers to develop their own electric road pavers – or to enter into partnerships for drive technology. Volvo CE has already led the way with electric articulated haulers, demonstrating that electrification works for heavy machinery as well.
Whether the Dynapac paver convinces technically and economically will become clear in the first practical applications. Key factors are battery lifespan, charging cycles, operational range and actual operating cost savings. For fleet managers: those active in urban road construction or public contracts with emission requirements should add this model to their watch list. For traditional highway construction sites with high material throughput, the diesel-powered asphalt paver remains the more reliable choice for now – until battery capacity and charging infrastructure are further expanded.
