Do we need to monitor road friction in summertime?
Work has started to investigate the importance of monitoring friction on Swedish roads in summertime. In a Nordic country like Sweden it is a fact that the friction is low in wintertime due to the weather situation and icy roads. In summertime it has been the understanding that friction has not been an issue. Modern brake systems and few incidents have implied that tire/road friction is in control. This has now been questioned. New road materials that have longer durability and the reduction of studded tires have produced the effect that roads are not loosening anymore; on the contrary the pavements are polished giving a lower friction. New building techniques with recycling have increased the number of bleeding areas which normally indicates lower friction. All this has given rise to the question if whether the rules have to be improved for summertime control of friction performance on Swedish roads. Included in this work is investigation of the need for friction measurements, the update of technical documents and suggest ideas on how to do more effective scanning of friction in summertime.
