Undersökning av beläggningsslitage vintern 2006/2007 i Stockholm
2007 (Swedish)Report (Other academic)
VTI has during a considerable time of years monitored the wear from studded tyres through full-scale tests and control sections. During the winter 2006-2007, measurements of the wear were carried out at several control sections in the region of Stockholm. The aim of these measurements was to study: - the amount of wear caused by studded tyres on urban streets in Stockholm, - the amount of wear caused by studded tyres on express ways outside Stockholm, - the number of private cars using studded tyres, - the relevance of the wear prediction model when used for urban streets.The result of the study shows that the wear of the asphalt wearing courses on the express ways around Stockholm has increased during the last few years even after compensation with respect to the increased amount of traffic. This means that every vehicle equipped with studded tyres wears away more material from the surface of the asphalt wearing course. One reason for this is that less wearing resistant aggregates have been used in the wearing courses on the express ways around Stockholm the last few years. Together with an increased amount of traffic it results in deeper wearing ruts compared with the winters in the beginning of this century. The rut depth caused by the traffic with studded tyres was 2-3 mm in the winter 2006/2007.
