Recently we completed friction and texture testing in the Catesby Tunnel.

The tunnel is the world’s longest indoor aerodynamic test facility.

Repeatability is very important in aerodynamic testing with small changes in environmental or atmospheric conditions having an effect on aerodynamic measurements. Another aspect which will have an effect on test measurements is the properties of the asphalt surface which the test vehicles travel over. Therefore, the tunnel operators required precise measurements of friction properties of the asphalt surface within the tunnel.
