Description
The vehicle-pavement interaction test facility consists of a large, rotatable, half-open drum inside which cassettes filled with realistic road materials are installed. Passenger car and truck tyres as well can roll on this road surface. The drum - with an internal diameter of 5.5 metres - is fixed to a central shaft by 12 spokes and is driven by a linear motor with a maximum speed of 280 km/h. The spokes are covered by sheet metal plates to avoid air turbulence and these are coated with sound-absorbing material. The central shaft is pivoted inside a frame structure with crossbeams.
The technical data can be found on the website of the faciliy.
