Rutting, depending on the wear of studded tyres, is a problem in the Skandinavian couritiis. Concrete pavements have a good wear resistance. In Ai.ustria they have recently developed a low noise concrete with small aggregate size and exposed aggregate. Earlier experiences have shown that the wear resistance of concrete is better with larger maximum aggregate size. This report shows how to make a concrete with small aggregates and still a good wear resistance. The most important reasons are that wear resistance also depends on the content of the maximum aggregate fraction and the glue between cement paste and aggregate.
