Existing materials will be recycled and reused

In the Oderbruch, a cultural landscape in eastern Brandenburg on the Polish border, a seven-kilometre section of the national road 334 is scheduled for rehabilitation between February and September 2025. Before the actual road construction work began, a careful search for explosive ordnance was carried out. The Oderbruch is a focal point on Brandenburg's explosive ordnance contamination map. Therefore, an explosive ordnance survey and removal of any ammunition found is mandatory before any construction work can begin.

Following clearance of the ammunition, the asphalt surface and binder course have been renewed since March 2025 from the junction of federal road B 167 with L 334 to the entrance to Letschin over a length of 7.1 kilometres. The 5.2-kilometre section from the bridge over the Alte Oder to the railway line before Letschin is being renewed using the high-level construction method. In this section, it is necessary to carry out a munitions search during construction, as the old packing layer underneath the small paving surface is also being removed. Before the new asphalt binder and surface layers are applied, a gravel base course will also be installed on an in-situ improved base course.

The base course will be produced using an innovative and resource-saving process that effectively utilises and recycles existing road construction materials. The existing unbound base course is first homogenised to achieve a uniform consistency. The small-paved surface, which has been removed and crushed on site to cover an area of around 31,000 square metres, is then reintegrated into this homogenised subgrade. The result is an improved base course that combines the benefits of both materials.
