Description

Short technical description: The VTI Road Simulator is a machine for accelerated testing of tyre influence on pavements under controlled conditions. The machine has six wheels rotating on a circular track covered with the pavement material. A separate motor drives each wheel. The diameter of the track is 5.25 m, giving a mean lap length of 16.5 m. The maximum width of track is 0.85 m. The wheels can be fitted at various radial distances from the centre of the machine and the machines axis can be slowly moved laterally while running by means of an eccentric device. This enables all wheels to be moved in an out a total of 60 mm. The lateral movement is especially important when using studed tyres, which would otherwise produce narrow ruts after each line of studs. Construction date: 1998 Last upgrade: 0
