Speedy Construction

Wirtgen Group machines rehabilitate Frankfurter Kreuz motorway junction in Germany. Wirtgen Group rehabilitated the roadways of Frankfurter Kreuz motorway junction one of the most critical road traffic hubs in Germany in less than 57 hours. The busy A5 motorway had to be blocked to demolish the bridge on the A5 at DarmstSdter Kreuz motorway junction. The process The roadway was repaired in both directions at six diffrerent locations, equating to a surface area of roughly 18,200 sq m. ´The project allowed no margin for errors, as blocking this stretch of the A5 in both directions a second time is not on the cards,´ said Burkhard Vieth, President of Hessen Mobil. The project planners allowed traffic to continue using the motorway on the national holiday. However, nine large milling machines and three compact milling machines started ploughing through the roadway surface in the night. The crews readied the first pavers and rollers while it was still dark so that they could commence the asphalt paving work on the completely milled sections before daybreak. STRABAG deployed machines from the Wirtgen Group while Hamm compactors and rubber-wheeled rollers were used to compact the rehabilitated hydraulically bound base course. V÷gele pavers and Hamm rollers handled the majority share of the asphalt paving work. The GRW 280 rubber-wheeled rollers from Hamm provided the initial compaction directly behind the pavers. These were followed by various tandem rollers, including all-wheel-drive machines from the DV series and articulated machines from the HD series with different operating weights. Despite heavy rainfall in the night, the new road re-opened to traffic in just 57 hours. (Communication by the management of the company)
