Last month, Dyckerhoff Beton delivered over 2,000 m3 of concrete to Bickhardt Bau of Kirchheim for the restoration of a bridge on the roundabout located on state road B263 in Wiesbaden.
Measuring 130 meters long, the bridge consists of 4 sections that form a single, continuous span over the roundabout.
Dyckerhoff Beton supplied the site with concrete from its Wiesbaden and Flörsheim plants, using a fleet of 14 truck-mixers that were all on the go at the same time. The pour started at 6 p.m. on Friday, 4 July and continued non-stop through the night until the last load was poured at 6 p.m. the following day, almost 24 hours later.
The class C 45/55 concrete was pumped at height by means of two pumps stationed on the roundabout, which was closed to traffic. The consistency of the concrete was constantly and scrupulously monitored both at the plants and onsite. The CEM III/A 42,5N cement used to prepare the concrete was produced by Dyckerhoff’s Amöneburg plant.
