A concrete pavement textured with artificial turf.

In the summer of 2017, ÖBA, which has been active in the German market with its Munich subsidiary since the end of 2016, was awarded a contract for the A93 motorway between Rosenheim and Kiefersfelden: the construction of the approximately-6km-long section between the three-way intersection at Inntal and the Reischenhart junction.

The new concrete slab, manufactured using slipform construction, extends over roughly 62,500 m². It is 12 to 15 m wide and 26 cm thick. Artificial turf was used to produce its surface structure: a total of around 20,000 running metres of joints were cut and sealed using a cold-sealing compound.

The company’s own construction site mixing equipment, with an average mixing capacity of 200m³/h, provided around 17,500m³ of road concrete for this project.
