Gebrüder Bantle GmbH is working on a large congestion-busting ring road project in Bösingen, Germany, excavating and building six kilometres of highway and nine bridges.
Bösingen is a town in the district of Rottweil, southwest Germany – a rural region situated between the Black Forest and Neckar valley. It neighbors the larger town of Dunningen and is well known by hikers and skiers for its impressive mountains.
Construction company Gebrüder Bantle GmbH embarked on a large road building project just a stone’s throw from its premises late last year.. The region’s main road – the B462 – a busy interconnection between the A5 Rheintalautobahn and A81 Stuttgart motorways, is used by 12,000 vehicles every day. A new ring road will help ease congestion for both residents and commuters.
The Dunningen project consists of a 6.4 km ring road, nine bridges and several access roads. Gebrüder Bantle is managing the foundation work as well as the road construction. The company specializes in road and civil construction and produces gravel from its two self-owned quarries and raw gypsum for cement production. It’s also a partner in an asphalt mixing plant.
Gebrüder Bantle was founded in 1956 and employs a permanent workforce of 120 people. Support comes in the form of a Volvo Construction Equipment (Volvo CE) fleet – including three L30G-Series, two L35G-Series, one L180E-Series and one L250G-Series wheel loaders, two EW160D-Series wheeled excavators, an EC290C-Series crawler excavator, one A40E-Series articulated hauler and a new G946B-Series motor grader – all acquired especially for this project.
“We appreciate the high quality machines Volvo CE offers,” says Georg Bantle, owner of the eponymous company. “They are reliable and durable – just want you need when you take on multiple projects.”
Building up the layers
To build up the road’s base layer, the Volvo G946B-Series motor grader first levelled the 11.5 metres wide of earth, then layered frost protection gravel over the top – 450 mm deep – using material from Bantle’s own quarry. Later the paver crew laid the asphalt base on the top along with the binder and surface layer – also using material from Bantle’s own production facilities. The new Volvo G946 motor grader is equipped with a grader control unit that has helped keep the project on track.
