scope:
This document 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, or to follow its evolution as a function of the number of polishing passes.
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.
