There are few Concrete Pavements in Sweden. Today there are only 68 km, built between 1991 and 2006. The earlier concrete pavements had a problem with much rutting due to the Swedish use of studded tyres during the winter months. The earliest road stretches in the 1990’s were therefor constructed with a focus on wear resistance [1-2] with high quality concrete and aggregate. Measurements after the first few years showed minimal rutting [2]. The two newest pavements, built 1999 and 2006 had lower quality aggregates and less margins on the concrete quality, barely meeting the requirements. They also show severe rutting at 10-15 years of age. This work looks into the relationships between concrete quality, aggregate quality and rutting.
