    Friction Curve


    ROAR - a Unit for Roads

    The Roar unit is especially designed for the measurement of pavement surface characteristics on roads. Relevant services are for example routine survey of highways for identification of poor friction sections, and testing of new tire designs for tire manufacturers.

    Roar is suitable for:
  • Public roads administration
  • Road research laboratories and technical centres
  • Public roads and aviation administrations
  • Insurance companies
  • Technical centres
  • Traffic accident investigators
  • Consumer product testing organisations

    The technology is based on a very simple idea: In order to stop or steer a car or an aeroplane, you need to use the friction force between the tire and the surface. The more friction, the better you steer and the faster you stop.
