Abstract
This European Standard describes a test method to determine the Polishing Degree (µPWS) and the Laboratory Skid Resistance µm at 60 km/h of surfaces. The test applies 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 & Schulze method.
