Vibration control in road construction

The planned northern bypass of the B472 Bad Tölz is intended to help relieve the eastern part of the town from through traffic; the construction project is being supervised by the Weilheim State Building Authority. In the vicinity of the planned route buildings of the company SAM GmbH are located with highly sensitive systems for metalworking, quality assurance and assembly, which might be disturbed/affected by the construction site vibrations. Thus, before the start of construction Müller-BBM Industry Solutions GmbH worked together with the Testing Office for Foundation Engineering, Soil Mechanics, Rock Mechanics and Tunnelling at the Technical University of Munich (TUM) to determine the vibration immissions to be expected at the company's machines and workplaces during the construction work.

Under the coordination of TUM, a special test field was set up at an appropriate distance from the company buildings, which was compacted using processes and machines selected by TUM. Müller-BBM Industry Solutions GmbH used high-precision accelerometers to record the resulting vibrations at a total of 15 measuring points on the site, in the company building and at machines and workstations.

The aim of the investigation was to define customised protective measures and construction methods based on the measurement data to achieve an undisturbed operation at the company SAM GmbH.
