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.

A concrete pavement textured with artificial turf.

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.

What ultimately counts in the construction business is successfully completed projects. PORR has many of these.
