Effect of the Combined Traffic Load and Weathering on the Skid Resistance of the Aggregates for Road Surface

The aggregates used for surface layers are of central importance for 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...
