Bituminous mixtures - Test methods for hot mix asphalt - Part 49: Determination of friction after polishing

This European Standard describes a test method to determine the friction at 60 km/h after polishing during a fixed number of passes on surfaces of bituminous mixtures samples. The samples used are either produced in a laboratory or are cores taken from the site. NOTE This procedure was previously known as Wehner and Schulze method (see [1]).
