Abstract [en]

Every year in the Nordic countries we are affected by winter road conditions. The roadsbecome unpredictable and many traffic accidents occur. This report aims to study thefriction on snow and ice and see how it is affected by different temperatures and surfaces.The friction will also be compared between tests made on outdoor tracks against tests onindoor tracks, and how the friction is affected after a studded tire passes and drives up thesurface. For this, several tests have been performed on Arctic Falls indoor and outdoortracks, where measurement data has been collected using two different ViaFriction carts.The data has then been analyzed in the program Matlab and compiled into several graphsand tables.

The results show that there is a clear correlation between a varying temperature and howthe coefficient of friction is affected by it. Indoor tracks do not differ significantly fromoutdoor tracks, but more tests or time may be required to make a completely safeconclusion. Finally, one can clearly see a big difference in the friction/surface when astudded tire has passed, in some cases up to a halved coefficient of friction for the drivensurface.
