Implementation of EN 12697-49 standard into practice

Popis výsledku v původním jazyce

European standard EN 12697-49 “Bituminous mixtures – Test methods for hot mix asphalt – Part 49: Determination of friction after polishing” describes the laboratory measurement of surface skid resistance. Measurements can be performed directly on cores taken from asphalt or concrete roads, or on test specimens prepared in a laboratory. Laboratory test specimens can be asphalt slabs made in compactors or samples made from splits of various fractions. Nowadays the results of friction measurement on various types of cores taken from roads are compared with the results of friction coefficient measured by the TRT dynamic test device. The goal was to verify the accuracy of laboratory measurement of skid resistance and determine the relationship between the values of road surface skid resistance and the intensity of traffic load. So far, the results of friction after polishing were measured using the Wehner/Schulze test device at the Vienna University of Technology. A new test device complying to EN 12697-49 was installed in the laboratory of the Faculty of Civil Engineering at the Brno University of Technology. The results measured using this new device are compared with those measured in Vienna to harmonize these two devices.
