The unique road simulator at VTI has been used for pavement wear studies for decades and has, in later years, also become an important resource for research on non-exhaust particles from road and tire interaction.
The simulator is a carousel-like equipment, where four wheels rotate on a circulator track. The pavement of the track and the tires can be chosen as preferred and up to 14 different pavements can be tested simultaneously for wear. Both temperature and humidity of the air in the room can be controlled, which is important for studying wear in the right conditions.
The road simulator is today used both for pavement wear studies and for studies on wear particle emissions and properties and how these relate to the choice of pavement and tire combination, speed etc.
The road simulator is available for research and development, in co-operation with academies and/or companies.
