The Osnabrück branch of Mull und Partner Ingenieurgesellschaft mbH was commissioned with the preliminary investigation of the road and embankment areas at the flood trough bridge near Rhede (Ems).
In the course of the framework contract between Mull und Partner Ingenieurgesellschaft mbH and NLStBV Lingen, preparatory investigations of the asphalt, soil and concrete material in the construction area are to be carried out at the old Ems bridge on the L52/58.
The background to the measure is the upcoming new construction of the Ems and flood trough bridge and the examination of possible recycling and disposal routes for the material that will be produced during the demolition of the old Ems bridge.
For the analysis of possible disposal routes of the demolition material, various laboratory tests have to be carried out. Various road surfaces (asphalt and concrete) as well as unbound layers of the road structure and soil material from surrounding areas that are to be used for the new bridge construction must be sampled and examined.
Under the direction of our colleague Patrick Lüke, twelve core drillings, six bank sampling, one topsoil sampling and one small pile driving borehole as well as various sampling of concrete rubble were carried out in the investigation area within two days.
