BAB A94 Isental motorway, project units 3 and 4

In this project, soil improvement measures were performed using the in-place mixing technique with 18,800 t of quicklime. In total, the ÖBA teams stabilised a volume of 1,450,000 m³. On each workday, 4,500 m³ were manufactured with a working depth of 45 cm.

The coordination between the advance performance of the customer and completion by ÖBA was a particular challenge.

The large construction area also made it necessary to efficiently coordinate the internal construction site reorganisations. Due to the severely constricted construction time, the teams generally worked with two recyclers simultaneously.
