Makrotexturens möjlighet att identifiera låg friktion: tillståndsmätning av vägytan


The Swedish Transport Administration want to describe the friction condition of the entire national road network. A nationwide friction measurement is practically difficult to manage and very costly, while we are already measuring road surface macrotexture. In this project, we test whether the macro texture (MPD, Mean Profile Depth) can be used to describe the friction condition of the road network. We have not been able to show this correlation but we present other interesting findings that give a piece of the puzzle for the Swedish Transport Administration how they can and should deal with the friction issue. We see, among other things, that the risk of low friction is greater on road sections with low MPD values and especially on roads with surface dressing that has bleeding patches. Furthermore, we describe the friction risks involved with different coatings and how these might be handled.
