The construction of the new bypass in the district of Kahren is being carried out in five construction lots. Since February 2024, PORR Transport Route Engineering, Eisenhüttenstadt branch, has been carrying out the fourth construction lot in a joint venture with Amand and Hentschke Bau. This includes the partial expansion of the new B 97 over a length of approx. 2.100 km east of the Kahren district.
The contract for PORR includes the construction of a gravel base layer over an area of 44,000 m², the construction of 7,000 m² of unpaved farm tracks, the construction of 8,000 m² of hard shoulders, as well as the construction of a new asphalt surface over 29,000 m².
In the future, Kahrener Dorfstraße will be routed over the new B 97, with no intersections. Work on the bridge structure is already underway, so traffic is being diverted via a local bypass.
Focus on InLine Pave technology
The modern InLine Pave method is used on an area of around 24,000 m². This compact construction method enables the asphalt binder and surface courses to be laid simultaneously in a ‘hot-on-hot’ process in just two days. This innovative method not only reduces costs, but also significantly shortens the runtime.
The team faces complex tasks in completing the project on schedule while meeting strict quality requirements. One of the biggest challenges is the precise synchronisation and coordination of all parties involved in order to carry out the staggered InLine Pave process efficiently and smoothly. It is crucial to optimally coordinate the delivery of the mix and the construction processes.
To meet the high demands, the PORR team relies on the project management tool SSO (Smart Site Solutions). This technology enables precise planning and coordination of the mix deliveries so that the various work steps can be carried out in the correct order and within the specified time frame.
