Effect of the combined traffic load and weathering on the skid resistance of the aggregates for road surface

摘要

The aggregates used for the surface layers are of central importance for the skid resistance as they are subjected to a constant combined load due to traffic and weather conditions. In the scope of this paper different aggregates are selected and two plate specimens are produced for each aggregate. Each is subjected only to a polishing load and a combined polishing and weather load. By comparing the results of the skid resistance measurements a statement is derived in the paper on the impact of a freeze-thaw effect on the short-term and long-term development of skid resistance.
